help with big wetsuit, ankle

Hello everyone. I've decided I want to learn how to surf. Im just having problems with the wetsuit. Im 6'5" tall and about 330 lbs. I dont exactly fit on the size charts. Any suggestions on where to go for a custom wetsuit? I dont mind spending the extra money for a good one. I hate buying something that would just fall apart. Ive looked around and see posts by short fat guys, and tall skinny guys, but no tall fat guys. I read an article that said O'Niell is supposed to have custom suits. But I cant find it on their website. I live in San Diego, CA.
I also would like to know how much of your ankle is used in surfing? Im in the military, and had a bad ankle injury. The foot and ankle has been fused together. I can move it up and down with no problem. But i will never be able to move it side to side. Im hopeing this wont affect my ability to surf.
Thanks for any advice!
