Possibly, but until you're 16, it's probably going to be very tough to get any job outside of mowing lawns and being a paperboy. If your family ran a shop, then that'd be your best bet, but I'm guessing that's not an option.
Your best bet is to ask. Some employer's won't just because of how little you can work for them per week, but you'll just have to ask around. There's a saying: "It's not what you know, it's who you know."
