Where can I a 12 year old girl get a well-paying job for after school in St. George Utah?

For good jobs you can: mow lawns, walk dogs, babysit,

put up signs around the town...etc. Sincererly: 12 year old from Canada. Well, due to child labor laws you can't get a real one but the person above gives the best idea! :D PS- I'm 12, too...though I'm from TX...
