@Philip Taylor I was merely using medical science as an example profession. It’s quite obvious that you don’t have any professional courtesy and downplay professions in which you don’t understand. Logo design isn’t just logo design. I don’t know what the profession of a public accountant entails, or a lawyer perhaps, so I’m not going to give advice on matters that I don’t especially have knowledge in.
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.
Drive for Uber or Lyft: If you're in a locale where you can find Uber or Lyft (or even one of the many competitors around the world such as China's Didi), you could easily make a respectable income. The hours are flexible and you can work as you see fit, making it perfect even if you currently have full-time employment but are looking to make some money on the side. 
Double check yourself, before you double wreck yourself. Make sure everything you send to a company, whether a résumé, an email or a portfolio, is good to go. Double check your grammar and wording, and for God’s sake use spell check! This is especially important when it comes to the company’s name. Don’t spell their name wrong and be sure to type it how they type it (e.g. Problogger, not Pro Blogger).
Make money on YouTube. People who love the spotlight and have other online hustles should consider creating their own YouTube channel. If you’re interested — and interesting — you can use the platform to market affiliate products, sell products you create yourself, or receive ad revenue for your informal tutorials or entertaining videos. Once you get the ball rolling, YouTube offers a partner program that can help you monetize your business further.

Ebay is a bellwether. It's been around since nearly the start of the online boom. But, like any other platform, success can seem fleeting if you don't know what you're doing. Selling items on eBay, professionally that is, can be an art form. Getting people interested in your auctions isn't always easy, especially when there's hefty competition and low demand for what you're selling.
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.
If you’re serious about making money selling things online, it’s pretty much impossible to not recommend Shopify. The platform gives you everything you need to get your online store up and running in less than a day including a custom domain, beautiful templates (so you don’t need design skills), secure payment options, and they can even take care of marketing and shipping for you. Whether you’re promoting your own products, designs, or curating other products for people in your niche, Shopify is the best option for powering your online store.
The peer-to-peer concept is coming to virtually every corner of human existence. That includes the hospitality industry. Through AirBnB you can actually rent out your house for various lengths of time for a predetermined fee. That gives you an extra income on your house and gives the visitor the benefit of having an entire house, rather than being crammed into a single hotel room.
A niche affiliate site often presents like an eCommerce store. To get started with an affiliate site, choose your niche then display products with pictures, descriptions, and prices, just as you would on an online store. However, when visitors click the ‘buy’ button, they will be taken directly to Amazon, to make the purchase. You then make an affiliate fee for sending the traffic to Amazon, but have none of the packaging hassle, or initial financial output creating or buying the products.
If you’re looking for inspiration, my friend Michelle Schroeder-Gardner of the website Making Sense of Sense has become the expert on all things affiliate marketing. Michelle earns more than $100,000 per month from her blog and the bulk of her income comes from affiliate sales. Michelle has had so much success with affiliate marketing that she even has her own course called Making Sense of Affiliate Marketing.
