Welcome to the forum! First off, I would encourage you to read the entire "New to Lyme..." thread at the top of the forum.
As far as pricing goes those sound awfully high. I am assuming he is a well known LLMD but don't know for sure (obviously). Make sure you do your research on any doctor you do find. My LLMD is $325 for first visit and $150 for subsequent appointments, but he is not well known and I am in a smaller town which are both big factors in pricing. Unfortunately for me there were ZERO LLMDs in my closed network HMO so I had no choice but to pay out of pocket to get taken care of. Pretty sad when you think about it. My PCP was convinced that since the ELISA was negative then there was NO WAY I had Lyme Disease. So much for dr continuing education.
Anyhoo, I am sure that Traveler or someone else will be able to provide some additional LLMDs and LLNDs in your area. Just make sure your email is enabled so they can send them to you.
Good luck and hang in there! You've found a great source of info and support!
