This has become a popular business model for online entrepreneurs over the past several years, and will probably just continue to grow in popularity. The best thing about selling online courses is that once you do the up-front work in creating the course and setting up your marketing strategy, you can get paid over and over again for work you do once.

Waiting tables and bartending are good ways to make extra money, but it’s not exactly if the work was easy. And if you don’t have any experience good luck applying at the nicest place in town, most restaurants require experience. Also if you have problems dealing with demanding, hungry people – STAY AWAY! The hours are late, sometimes you won’t make any money. Especially right now, starting at new place will be difficult, if you can get hired expect to be the first one cut every night (aka less money) as those with seniority will want to stay. It still is a good deal though. I’ve put myself through college (chem major) without loans, never lived in the dorms, and I have about 10K in the bank. I will continue working in the restaurant biz even after I have a “Real Job,” the extra 10-15K/year for part time work is worth it.

It's a little more involved. Companies, especially those with stores, will want to get the opinion of the customer as they go through a transaction. For a bank, it might be opening up an account. For a retail clothing store, it might be trying on a shirt and checking out. Sometimes it's just calling up their customer service line with a problem and seeing how the representative treats you.
Blogging is a great side hustle because you can do it at your own pace anywhere you want. It's not a quick and easy way to make money, but there are a lot of ways to make money side hustling while blogging. You can sell advertising, become an affiliate for other people's products, sell your own online product, and more. It does take time to build up an audience to be able to make a decent amount of money, but once you have a large following, you could earn over $15,000 per month or more (we do).
You'll also need ecommerce software, fulfillment software, worry about warehousing, customer service, refunds and so on. But that's not all. You'll also need traffic. Think search engine optimization, Facebook ads, and other social media campaigns. Sound like a lot of work? Sure, it is. Especially if you do it all on your own. You could opt for Amazon's platform, which might be the easier route. But, then again, at the end of the day, this is a serious business, which could produce significant profits. So you're either all in or you're not. 
You can set up a website, gradually build up the content (articles, videos, podcasts, etc.), then eventually monetize the site through advertising, affiliate marketing, or even the direct sale of specific products or services. Even better, you can generally find whatever services and technical assistance you need online and free of charge. Later on, when your site develops a reliable cash flow, you can begin working with paid providers who can take your blog to the next level.
I understand the need to build a profile, but again, after several minutes of answering repetitive questions, I am either told I don’t qualify, or I’m sent an email which contains a broken link, or…you get the idea.  I would gladly spend 30 – 45 minutes answering a survey, submit, and earn the amount of $ it said it would pay.  But, these last four days have been a royal waste of time. 
Blogging is also one of the cheapest ways to make money online, aside from the time and and intellectual input that you have to invest. As you begin to make money from your blogging efforts, you can easily outsource for greater scalability. I also use Bluehost and I like the fact that it seamlessly integrates or interfaces with WordPress. You can set-up a domain or subdomain in minutes and start blogging in seconds. I love it!
Sell stuff online. If you have high-quality items to sell, there are a slew of online marketplaces you can use. Just make sure you understand the fees associated with your sale before you take the plunge. Where neighborhood Facebook pages and Craigslist ads are free, many online marketplaces or consignment shops charge for ads or require you to fork over a percentage when you make a sale.
A spin-off for web designers is to offer a landing page creation service. Well optimized landing pages can be the difference between a successful and a failing business. And, as creating the perfect landing page isn’t easy, this is a service many businesses are prepared to pay for. I know people who are earning 6 figures per year and all they do is create landing pages for businesses. There’s serious money to be made.

Walk around your neighborhood or town and I’m sure you’ll see tons of great local businesses with terrible design. However, with increasingly easy-to-use tools like Adobe Illustrator, Venngage, Stencil, and Visme, just about anyone with a creative mindset and a good amount of motivation can start making money online by being a graphic designer for local companies.
ThredUp. Their tag line is "secondhand clothes, firsthand fun." And they have to get their clothes from somewhere. Are you catching on? You are that somewhere. The website sells women's and kid's clothes (sorry, guys). You send your clothes in a ThredUp bag with a prepaid mailing label, and ThredUp will decide the value. They're looking for nice clothes and popular brands, and there's a fee if your items aren't accepted. So if you have clothes better suited for a yard sale, hold a yard sale. But if you have quality outfits you no longer want, ThredUp will probably pay you enough that you can buy new threads.
If you live in an area where Uber or Lyft operate, why not become a driver? If you're looking to make some short-term cash, you can definitely rake it in by working for one of these popular car-hire apps. As long as your vehicle fits within the specifications of their program, and you have a clean license, you could do this on the side, especially if you're in a crunch for cash.
If you are a professional photographer, or have a real flair for photography, then selling your images on other sites could be an idea. This could be done alongside your own photography site, as it is a good way help get your work viewed by a wider audience. There are numerous stock image websites to contribute to, but choosing a popular high-end site like Shutterstock should ensure your photographs make you some money.
Consider your expertise. If you take the time to reflect on your experiences, you will realize that you have more knowledge about which to write than you might think. Begin by listing three assets that define you, such as your profession, a special hobby or a personality trait. Next, list three things that inspire you, such as religion, education or charity. Finally, list three of your dreams, such as getting married, traveling or spending more time with your children. These three lists should give you many ideas of topics about which you can write.[13]
There’s an excellent chance that you have one or several musical instruments sitting in storage that haven’t been used in years. Perhaps it’s a leftover from when you were in school, or even from your days playing in a band. Whatever the reason that you have it, it’s probably worth money if you can sell it. Brand-new instruments are ridiculously expensive, so people often look to buy used equipment instead, particularly if they are novices.
There are numerous printing companies that will print your designs onto not just T-shirts, but also hoodies, hats, posters, cushions, bags, and phone cases, to name a few items. These businesses also offer fulfillment services. This means that you promote the merchandise on your own site and once you sell a product the printing company will not only print your design but also send the item directly to the buyer. So all you have to do is concentrate on the marketing and selling of your products, and the fulfillment company will take care of the rest.
Become an Amazon Associate and then use Keyword planner to find an in-demand niche: With more than a million different products to choose from and up to 10% commission the sales you drive, Amazon’s affiliate program is a great place to get started. Browse their available products and see what connects with you. Or take it a step further and use Google’s Keyword Planner to quickly check how many people are searching for a specific term. With affiliate marketing, the more relevant traffic you can pull in, the more you’ll make off your site.
A site called User Testing will actually pay you a fee to evaluate websites. It typically pays you $10 for each video that you review – which typically takes about 20 minutes. If the work is there, and you are particularly good at it, you could earn up to $30 per hour. That’s a pretty solid pay rate for a work-at-home job. You wouldn’t have to work a whole lot of hours to generate a decent part-time monthly income.
OneOpinion— signing up is completely free, as it should be. This survey site, like many others, works on a points system: 1,000 points = $1. Once you reach 25,000 ($25), you can choose to cash out via PayPal or an Amazon gift card. OneOpinion also offers product testing, which means you have the opportunity to test new products at home before they hit the market.

Using Fiverr is a great way to pick up work. Once you have signed up you can advertise your services. Fiver allows you to create your own gigs, whether you are offering web design, digital marketing, writing, or something else. You can choose how much you want to charge (it can be more than a fiver) and people will then contact you if they are interested in working with you. Fiverr will not only help you get experience if you are just starting off as a freelancer, it will also help you earn some extra cash.
Evaluate Web sites. Another way to make extra cash in a short amount time – $10 for about 20 minutes of work – is to sign on with UserTesting and evaluate Web sites. You need a computer with a microphone and Internet connection, and you’ll have to fill out a one-page demographic profile. You’ll receive work if your profile matches that of the target audience of sites being tested. Then it’s just a matter of using UserTesting’s screen recorder, which you'll need to download to your computer, to record your verbal comments and on-screen movements as you click through a site. Site owners typically are looking for feedback about whether the Web site is confusing to navigate.
Etsy. Are you crafty? This is one of those websites where, once again, it helps if you have a real skill. If you're artistic and are the type of person who can make custom jewelry or refrigerator magnets with the best of them, Etsy is the place to sell it. For the rest of us, we must find another website to go to, so we can earn money to buy things from the crafty people at Etsy.
