You're open to the same kinds of positions as everyone else with just two more limitations - at home and disabled.
What can you do? What skill sets do you already have? How does that turn into making money at home? No one can list every job you can do at home. There's too many jobs to remember them all, but it does take creative thinking. You already know what you can do, so what kind of business would be interested in your talents? Once you figure out that list, figure out what they want from you? I can't really tell you how to do this as much as I can show you how I've gone about doing it.
Before becoming disabled, I had jobs doing telemarketing to business, typing, office work, filing, dealing with mailing out everything from large packages to tons of bills, to sales pitches to previous customers, I had a stint at an ad agency, so I learned copy writing, and how to make pamphlets and other small marketing pieces. And, because I took a course in college about business writing, I learned how to make a great resume and how to write small business contracts. With all that past experience, before I became disabled, I started my own business doing secretarial services, making resumes for people, and small marketing material for people. To do that, I needed to learn how to start my own home-based business, so I read books for a year, and found a place online where others with the same kind of businesses (including billing people) to learn how. I learned marketing the most. That's key to working for yourself, how to get the word out for cheap. I used guerrilla marketing which is something a guy named Jay Conrad Levinson. http://www.gmarketing.com/
Back then he only had three books. lol
But things I did -
typed student papers
made pamphlets for business just starting
typed briefs for lawyers
typed meeting minutes for an architect
created a 14,0000 address database for a guy who ended up being a swindler.
typed words for walk-in (conspiracy theorist. The guy was scary creepy, who actually thought our local concert venue was a conspiracy, because it was named after a now defunct bank called First Union and he didn't like it, so assumed the bank's initials meant something. lol)
There were creepy customers, but I'm married to a guy 6'2" tall and big, so he looks scary. I had the customers who scared me come and meet him, to drop any idea of causing me harm.
The only reason I can't do this now, is because I can't keep my living room clean (that's where customers came) and do the work whenever needed. But, I hope the story gives you some ideas on things you can do at home. It's all a matter of being creative with the skills you have, and then learning how to open your own business.
Other choices would be making websites, making calls from your home, making websites more noticable on search engines, writing articles for others, or taking calls for one-man businesses, like office cleaners, carpet cleaners, plumbers, or electricians, selling crfts on Etsy Bitsy, or whatever you can make at home to sell.
