My xT and my current T are both Christian counselors. Even though when I called and asked their fees or if their fees where listed on website, etc. there was not mention of it, they both had sliding scale fees. Did you consider asking about that? Also, sometimes churches will refer you to a counselor that their church uses a lot and may contribute to your fees. My xT website talks about churches referring and says that there is still confidentiality as what is discussed in session is not disclosed to church...

just some ideas since I had nothing to contribute regarding email counseling.
