Where can I find specific teen jobs?

I live in Milwaukee, Wisconsin. I am 16 years old and I'll be 17 in May (less than two months). I've applied for a few places and I have good qualifications. I even have a resume because I've done a couple things with my life. Numerous programs (one at Marquette) and a Journal Sentinel Internship. I just applied for Kids Foot Locker, Sentry, and Dots today.(I'm not even old enough for Dots). I love starbucks, but can't find if I'm old enough to work there. I'm looking for more places to apply because I really do want and need a job. I'm willing to work in Milwaukee or Wauwatosa. I have grandparents to stay with in Wauwatosa if I can find a job there. Someone please help me...
