If your into baseball, Umpire for your local little league. Those generally pay about 20 dollars per game. thats what im going to do when im 14.
Or maybe you can be a bus boy at a diner in your town cleaning up the tables. Although i wouldnt do that considering i dont like to serve or clean up after other people let alone myself.
walk dogs, clean up their crap, shovel sidewalks...all the neighborhood jobs you can get.
good luck with your search.
