It was difficult in my area, which is conservative (a mini-Bible belt).
What happened is that I came out to my regular counselor who had worked with me for a few years, through my depression and social anxiety, and I loved and trusted her, so finally I told her the last big thing I had left that was really derailing my therapy...
... and she was there for me. She always has been. She's been sort of a surrogate mom to me, since my actual mom just never understood me nor really had the ability to do so even when she tried.
Bless her heart, she admitted right up front she had no idea what to exactly do to help, except provide a safe place for me to talk and work through this issue and come to decisions. She had worked with homosexual clients, so she understand some of the typical dynamics involved in the secrecy of a large issue like that and its impact on a marriage when it finally comes out, as well as many of the spiritual problems involved (deep feelings of shame, etc.) That helped her alot with the basics.
Meanwhile, she contacted everyone she could to get experience; she went to seminars in our area when she could that involved trans issues; and when she located another counselor who had dealt with some trans patients (that was the best she could do), she advised me to see her even though it meant eventually not seeing her.
Not being able to get specific "gender help" (i.e., someone to walk me through practical issues) probably has been the largest thing I've missed; but I was fortunate I had a counselor who loved me enough to stretch herself and be there for me. I am the sort of person who reads and studies and researches and has a good "big picture" sense, which I am glad for since she couldn't provide that sort of guidance, but her basic love for me as a human being went a fair distance even without the specifics.
I'm not sure what my point is here, except to say all is not completely lost if you can't find a "gender counselor" specifically in your area. If you CAN find one, though, I would get one... and not someone who just bills themselves as such, but someone who has actively helped transgender people from the begining stages THROUGH transition. There's a lot of knowledge accumulated in that sort of experience, and it will also help you with local contacts... that was something else I had a heck of a time figuring out and why I ended up having at least one disastrous moment.
