I would use google to find the top rated gastroenterologists in the area and then call those ones. You are asking for very specific things so yes it will be hard to find one that you like.
I've tried that but am finding resistance,but thanks anyway.
Welcome to the gastroenterology community! You ask a very very specific question and it is very unlikely that someone on this community knows the answer to you question. I would recommend calling local GI doctors and talking to them and seeing which one would go along with your requests.
OKAAYYYYYYYYYYYYYY....SO I SUPPOSE NOONE KNOWS??????
