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 selling your own products, designs, or curating other products for people in your niche, Shopify is the best option for powering your online store.
There are several to choose from to make money online. At kgbanswers.com and JustAnswer.com, you become an expert after taking a brief test. At these websites, a customer asks a question and receives an answer from an "expert." At kgbanswers, answers come via your smartphone. At JustAnswers, answers come via email or text message. Both offer subscription and per-question alternatives.
If you’re looking for more serious work, you could try your hand at a site like Upwork, where you can find bigger projects in the web and graphic design arena. Again, competition here is also fierce with many people attempting to undercut others. If you don’t have a solid portfolio and track record, you’ll find it difficult to make very much money at all.
The difference between Amazon and EBay is that EBay (though still filled with new items) is seen as a used marketplace between individual parties, whereas Amazon (which is filled with offers for new and used merchandise from the 3rd parties) is viewed as a Wal-Mart-type superstore. As a consumer, this difference leads me to use Amazon, so it only makes sense to target on my own demographic.
Next, you’ll want to pick a WordPress theme from somewhere like ThemeForest, Elegant Themes or OptimizePress. This is the barebones design of your site, which you can then customize with your own branding, copy, and images. That being said, you don’t want to cheap out. It costs less than $100 to buy a theme that will make your website look professional (and you can upgrade to a completely custom design once you get the business going).
