I love that you are fixing things when other people would just throw them away as unsalvageable. I know some communities have repair workshops, or repair cafés. Maybe check if there is one near you, or if not, you could maybe start one? As I understand it, it generally works on a donation basis, and people who know what they're doing offer their time to try and teach others/help them fix things, and the donations go to those people/supplies for the event. More money for the fixer if they are outright fixing a thing for someone, but the emphasis is on teaching people to fix themselves. Though of course, the "rules" would be different for each repair workshop.
