Best way to train for MMA with a limited budget?? How to be like Rocky?

Ok so I have been doing martial arts since I started doing Muay Thai when I was 11. Now I'm 22, I'm fresh out of college, and I am broke!!! Anyway I am getting on my feet and getting my money/work/bills stuff sorted out, but it will be a while until I can train at the holy glowing MMA gym we have here in Hollywood, because its seriously expensive. So I want a Rocky-brand training regiment, but for MMA. Right now I have a membership at a gym so run down (its in an abandoned jail), it make's rocky's impoverished gym look like a 24 hour fitness. But it has the basic weightlifting equipment, bench press, squats, dumbells, barbells, stationary bikes, etc. And they have a serious boxing retinue. I have a boxing trainer who is doing wonders for my punching, my power, and my range. But I am afraid I am letting my Muay Thai and BJJ experience go down the drain while I just do boxing. I've got very little money, basically living day to day, but I still want to train like a champ. Any ideas??
