I only know about electrolysis, not about laser, but many electrologists who specialise in trans-people will do genital hair removal as well, though usually they charge more for it. Mine does and I would refer you to her - but unfortunately she's here in the UK. Sorry hon.
All I can suggest is that you trawl websites and go to support groups - the other people attending might be able to refer you. Also, my electrologist found her first clients by going to support group meetings and handing out business cards. I'd imagine at least a few would do the same.
