Do you live in a neighborhood with a lot of people? Within walking or biking distance? Offer to do work for people if they pay you. I see you live in michigan, you could shovel lots of snow for people, driveways, sidewalks. Then when spring time comes I'm sure there will be a lot of yard work there too that people wouldn't mind paying a young kid for. Cut grass, plant flowers, spread mulch.....etc.
Most people will appreciate the fact that you are young and you have the ambition to do work so you can earn money. I'm sure they won't mind paying you.
