What can i do to start my acting career?

I am 17 and i want to become an actor really bad. I have done a few plays but nothing really major. I can play the guitar, drums, french horn, trumpet, and i can sing. I live in a fairly small town in Oklahoma and want to find that one breakthrough person that can help me achieve my dream. If anyone is or knows someone that can help me start my career just e-mail me. Thank you
