I don’t know if he’s making good money or anything but in my town of around 100k there is one guy who is a bit of a jack of all trades (and to me it seems he could be a master as well, but I wouldn’t know). He does stuff like copying keys, leatherwork, sharpening knives and so on. This is the guy you go to if you need some more obscure thing done. Might be something for you if you like that sort of stuff.
