Maybe you don't need money. Could be enough to set up a website with accounts and a system that gives you "karma" for each bug you remove or a feature you add.

Maybe you don't need money. Could be enough to set up a website with accounts and a system that gives you "karma" for each bug you remove or a feature you add. Amount of karma depending on the bug/feature and maybe an additional voting system for users to push their favourite feature or most annoying bug. Having a lot of karma on such a site may even be interesting for your resume when you apply for a job.
