need guidance with finding a mma gym

I have decide to follow my dream of competing in mixed martial art. Martial arts have been a passion of my since childhood and im still young of enough (20) to start. I lived near the raleigh area and take college class in wilson but Im willing to drive out 90 mins to 2 hours in order to get the best training. Any advice on the best gyms and any other useful infomation on start my path would be extremely helpful.
