How to become a pro fighter?

Can you become a pro fighter without any formal training? I've been wrestling since I was 8 (now 18), I've done some boxing and kickboxing with my uncle who used to own his own gym, and i've read lots of jiu-jitsu books, watched dvd's, i've grappled and sparred with some wrestlers at my house on the mats, and all i do is watch mixed martial arts and apply that to my wrestling, when i spar and grapple with friends, etc.
