Watch other people’s kids along with your own. There’s a good chance your friends who work outside of their homes would be thrilled to have an experienced parent watch their children while they are at the office. It can be manageable if your friend in need has only one or two kids. Plus, the new playmates will help keep your children occupied for a few hours. Pay varies widely based on where you live and the ages and number of kids you'll be watching, but babysitters and nannies typically can make up to $10 an hour in small cities and much more – even double that hourly rate – in larger cities.
Creating a jobs board website can be another profitable venture. The ‘jobs’ field can be quite saturated, so it is important to find a niche that is still crying out for a jobs board website. Monetize this type of site by charging businesses to list their jobs on your site. Those searching for jobs could also be charged a fee to access the higher paying job adverts.
Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt). Do keyword research to see it others are interested in the topic. Find out if a domain name is available that matches the keyword 100 percent. 
In my (unpopular) opinion, getting a raise is harder than getting a promotion. Think about it from your boss’s perspective, would you rather a) pay more money for the same service, or b) pay more money for additional responsibilities. Alas, if you feel you’re overdue a raise, check out Dr. Randall Hansen’s article on Getting the Raise You Deserve. There are some really useful strategies there.
Shopify is another great option if you are wanting to create your own eCommerce store. Shopify is arguably easier to set up than WooCommerce but will give you less control over your storefront and cost you more long term. However, if you have little to no experience of creating websites or using WordPress, or you are working to a very tight time schedule, then Shopify may be the perfect eCommerce platform for you.
Clearly, there's a lot of demand on Amazon, and if any product is going to sell, it's going to sell well on Amazon. But the goal here is to source the right products that will easily sell at the world's largest online retailer. Generally, products between $10 and $50 sell very well here. Just be sure to do the right market research before jumping on this bandwagon.
Selling digital products can be just as successful as selling physical products. Graphics, software, eBooks, design elements, sound effects, songs and videos are just a few types of digital products that are in popular demand. So if you can turn your hand to creating digital products, let’s have a look at how you can make money online from this skill…
Start a bed and breakfast. If you live in a popular resort area or own a historic property, a B&B might be the perfect side hustle. Not only can you work at home with this career, but you’ll also score some tax write-offs in the process — although most innkeepers caution that the profession requires a lot of hard work and is more of an attractive lifestyle than a money-making pursuit.
OfferUp.com. If you don't have the energy to hold a yard sale, OfferUp may be the next best, profitable thing. Sell one thing at a time. Take a picture of what you have, put down a price and hopefully somebody nearby will see it online, love it enough to buy it, send you a note and you'll meet – in a public place, OfferUp's website recommends – and you can get your cash for whatever you're selling. Of course, you might ask how this is different than selling on, say, the ever-popular Craigslist. Some users claim that it's an easier site to post on, and members have profiles, so you can rate each other and get a better sense that people are who they say they are, which isn't always the case on Craigslist. Nevertheless, you'd still do well to use common sense and buy and sell OfferUp items in public places rather than at someone's home or in the dark woods.
In the freelance writing gigs, it appears about.com is gone (gasp!) it links to a site called dotdash.com. I tried going to about.com myself to make sure it wasn’t a bad link and sure enough it took me to dotdash.com. In their careers section they are currently hiring some freelance (contract) tech writers but that was the only “freelance”/contract position(s) they have. Thought you’d like to know.
Here’s a good example of how lead sales can work in real life: My second website, Life Insurance by Jeff, brings in a ton of traffic from people who are searching the web to find answers to life insurance questions. While I used to have the website set up so I could sell these people life insurance myself, it was a lot of work to process all the different requests and clients. As a result, I started selling the leads I gathered instead.
