I could work in a movie theater or something similar, but then I’m back to making state minimum wage instead the almost double that I’m currently making.

You could own a theatre. You could also create a local film festival, even if that means just booking the community room at the library and screening public domain silent films to start with. Or if you want to make a job out of it, maybe you can snag the screening rights to some indie/deep backlog films and do a traveling film festival, maybe setting up in small towns where there isn't already a ton going on where you could also get the venue for cheap.

There's also companies popping up that have bought the rights to reprint deep back catalogue films. Like I recently heard about one that buys the rights to reprint B movies from the 70s and 80s on VHS, so apparently there is a market for that kind of thing too!
