Where are you located? The best way is to travel to seminars and to the nearest moon and start training in the system with someone. Almost everyone in the U.S. now has a moon in somewhat reasonable travel distance that lets them train at a moon even if it's only on a monthly basis.
If you are the same Tyler Holmes from TMA in Oklahoma that pops up in a google search and fought MMA earlier this year, you have a moon right in Altus, OK as well as some up in Missouri. So, they have you covered!
