Upwork: This website offers a great marketplace for selling just about any professional service. You don't need a merchant account, a website of your own or anything else for that matter. All you need to do is be able to provide a high-quality service at a reasonable price. But be informed, you will have to compete with many others that are constantly bidding on open jobs. 
People are turning to audio and visuals when it comes to technical subjects. However, you should consider doing an ebook first and turning it into an audiobook through a resource like Audible's ACX platform. You can hire a producer either through a royalty share program, so you don't have to shell out upfront cash, or you can do a pay-per-hour hire as well.
Considering that you have a finite amount of time, passive income should make up a large part of your work. If you're serious about generating any semblance of income online, then passive income should be one of your sole goals and ambitions. Why? Wouldn't you prefer to do the work one time and get paid repeatedly as opposed to relying on your time to generate that income? Invest the time at the front-end so that you can reap the benefits on the back-end. This means putting in a bit of sweat equity and not getting paid today. Rather, you'll get paid somewhere down the road. And you'll continue getting paid whether you keep building that passive income stream or you stop. 

Determine if you have the equipment/tools to make your home-based business a success. Knowing what you need in terms of tools should be included in the cost. In some cases a simple computer and certain software will do the trick. However, if you are running another type of business, such as an embroidery or catering company you may need to purchase certain equipment to get your home based business off the ground.

Start With Freelance Copywriting Platforms. When I first started working as a freelance writer, I was shocked to discover just how many freelance writing jobs were available for the taking. You can find work on dozens of reputable websites, from general-purpose freelance platforms like Upwork to writing-only portals such as Textbroker. These gigs don’t pay handsomely – starting writers earn little more than $0.01 per word on Textbroker, for instance. And the writing is often monotonous: lots of product descriptions, ad copy, press releases, and throwaway blog posts. But they’re great for getting your foot in the door, learning what editors expect from freelance writers, and becoming a better writer overall.
Try flipping houses if you have experience with making home repairs. As you may know from watching popular home improvement shows, flipping homes involves buying up a lower valued property that needs work, and then fixing it up for resell. To get started, you’ll need to have financing either through a bank a partner. Then, you can buy a property that’s priced below market value. After you renovate the property, you may be able to sell it for a profit.[13]
Are you a professional in a field that can help answer questions for people looking for your expertise? Websites like JustAnswer and LivePerson match you up with people looking for answers to technical or professional questions. You can make money online by simply answering these questions and providing the right information to people based on their individualistic circumstances.
Join a startup accelerator: Another great option is to apply to a startup accelerator like Y Combinator, 500 startups, or TechStars, where a group of investors will help coach you, connect you with potential partners, and provide startup cash in return for a small stake in your company. The competition is tough to get into these, so don’t rely on them as your only path forward.
Take it seriously. Yes, you’re applying for an online job. Yes, you can do the work in your underwear, but that doesn’t mean it’s not a “real job”. You must treat it as such or they aren’t going to treat you as a serious candidate. You aren’t the only one who wants to work in their underwear. In fact, the competition online is likely higher than it is in your local area.
