This ties right into what my advice was going to be: start a consulting practice to help organizations make their software accessible by performing audits and providing recommendations. Come up with a menu of services w/pricing and post them on your site. An option that's a few hundred bucks or less could be a good mechanism for generating new clients. This is a service that people would use, and because you're a stake-holding user it makes it much more valuable than one of those companies that runs an accessibility tool and summarizes the results. Having worked for a software consulting company that's built accessible software in the past, your testing service offering would be valuable but probably not something that a full-time position would have been created for.
