How would you become a disney actor ?

well basically, i really want to become an actress on Disney channel, but i dont know how. a lot of disney stars originate from texas (cody linely, demi lovato, tiffany thorton, hillary duff, selena gomez..) and im also from texas and i was wondering how did they get their break so easy from Texas??but. the point is that i want to know how i could get an audition with Disney management, and what skills would be required for getting a role on a disney sitcom (and yes i know its not easy!) the only acting experience i have is from school drama elective, but do they look for your background in acting, or your actual acting ability-because alot of the stars have some sort of background experience. can somebody please answer these questions with detail. and yes, i can act.
