Tutor students. Many families prefer the flexibility of using an online tutor. Depending on your background, you could be simply helping a child with homework or providing college-level support. You need to have your own computer and high speed internet. Experience required differs among companies. Some require “strong experience,” while others require a specific educational background. However, most companies do require a college degree.
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. 
Are you just starting your first online business and not sure whether you want to be a product creator or affiliate? Personally, I prefer being an affiliate.

If you have an e-book or online course that you'd like to promote, ClickBank makes that easy. Once you sign up as a vendor you can list your product with them and set the commission percentage you are willing to pay to anyone who chooses to market and promote your product for you. Once your product is listed, other ClickBank users will start promoting it on their own websites. This will drive traffic to the sales page on your website and hopefully result in sales.
Etsy: While Etsy's popularity has declined recently, it's still a great resource for selling handmade items online. No need for complex ecommerce sites or merchant accounts or any sort of automation. The company takes a commission of every sale and charges a small listing fee per item. But many still use Etsy as their primary source of income. The best part is that you can also sell digital products on here such as poster designs.
But don't make the mistake of thinking this will be a passive source of income—you're on call whenever you have a guest and you'll always need to keep the place clean for incoming visitors. On top of just renting on Airbnb, consider offering your guests paid add-ons, like Lauren Gheysens', Royal Day Out in London, England—where she gives visitors a local's only tour of the city, complete with bespoke 18th century costumes.
21. Facebook – Facebook swap shops are great for selling things locally. It’s like CraigsList, but a little easier. You simply search for swap shops in your area and ask to join the group.

You can generally expect to get about what you would get at a yard sale, maybe a little more.
If you're interested in online marketing, setup email software and create a lead magnet that you can use in your sales funnel. Then, build up that list.

You will need to deliver value and not pitch them on every email, but it is a very achievable goal in a short period.
27. Sponsored/paid posts – Many blogs publish sponsored and paid posts. Sponsored posts are basically just posts about a specific brand, product or service. A company will pay you to publish an article about it. It’s similar with other paid posts as well. Your basically selling the spot for the article on your site. If you decide to take this route, you’ll want to build your traffic before you will get many offers.

The second (and cheaper) path assumes that you have the design and dev chops yourself to build your dream software.
