Whats a good job that requires makeup and cosmetics..?

Once I get settled down at my new location, I would really like to work in something that involves make-up and knowing about cosmetics for part-time or full time while im in college. You know..to get me through school. I have always loved make-up! When I was a teen I would do my friends make-up for free and I always spent my money on make-up. I wanted to take classes or go to school to get better but I was too young to get in. Anyways, I dont want to be a cosmotologist as my proffesion. However, it would be amazing if I could get a job at a store, dealing with cosmetics and doing people's makeup. I need advice, I cant afford to go to a beauty school, so what are some ideas that you can give me to get a job like this in the future. Im talking about working at sephora, or makeup department for jc penny or macy's. Thanks
