Wash cars or bikes if you have a big enough driveway. Gather some sponges or old rags, towels, car washing liquid, a big bucket, and a hose and set up a washing station in your driveway for a few hours on the weekend. Scrub each vehicle, focusing on any dirty spots, rinse it thoroughly, and buff it dry with a microfiber towel. Charge $10 to $20 per vehicle.
most of these site you have to be older then 18, so thus you couldn’t do any of them unless in your parents name, also you would need their credit card or pay pal account, which i don’t think any parent would let their kid have that account, best advice i can tell you is to try working in lawn care, good for you wanted to start working young, i know how hard it can be living in a small town with poor parents, mabye ask around for idea, beware of the net though, net jobs are mostly scams and they onces that aren’t you mostly have to be 18, mabye if you don’t need a permit in your town sell cookies, or your old toys in a yard sale. cleaning jobs, are good. good luck, i know what it like being you, work hard
