talk to your family.
maybe depending on where they work they could help you out and get you a job where they work. i used to work with my mom, then again i was 17..
really the only place that will let you get your foot into the working field is like a grocery store i think.
most places you need to be of age to work for safety reasons and what not.
what about baby sitting? you could put up fliers where grocery stores are in bulletins and maybe you would get quite the list of call backs.
if theres no other way of getting work, that might be an option..
