I used to manage a small retail store in the mall back home. Every summer we would go through the local office of the texas workforce commission and hire teens for the summer. It is a special program that pays them well and they get training and assistance finding a job!!! We loved it! Although we personally never had anyone under the age of 15 work for us, I am fairly certain they can start with that progrm at age 14.
Check with you local workforce commission office and see if they have it up here!!!
Hope this helps and good luck!! I know I started working at age 15 and wouldn't have traded it for the world!!!
hugs and blessings
