I paint mailboxes in my community. I found that my home owners association guy will give me the mailbox numbers for free, so I take it all apart, sand it, paint it, put it back together, then take the number plaque hone with me sand it with a power sander then prime it, paint it, and glue the numbers on with epoxy. Costs me $4.50 in supplies per box but I make $40 per box and get about 3 jobs per week on average. It depends how old you are to what you can do. I am also going to be a bag boy at a grocery store this winter, and next spring an umpire at a local baseball field for youths age 5-10.
