You're just describing a consulting company that targets low income clients. It would be a hard sell because the market is limited and in order to stay in business you need either more customers or charge more. This wouldn't be bad as a part time gig but I imagine it would be hard to run as a full time business.

Edit: You are going to compete with those who can also develop that are in the start up scene as well as those on upwork. Taking equity would also make it a harder sell and limit your market even further. Nobody is going to want to hire you to make their product if you are already invested in their competitor.
