Your age makes a big difference… in NJ, you can get your working papers at 14, but some jobs require that you are 16, 17 or 18. My son’s first summer job was helping at a furniture warehouse and deliveries. At 17 he got a job at a car dealer… he cleaned the customer waiting area, and then moved into the car wash. He’s been there for over a year now, and earns a decent amount for his age.
