Yeah, that's a problem in a lot of places (most places, actually). There are very few vets around that are proficient at treating herps, or even want to treat them for that matter. There are a lot more of them now than 20 years ago, believe it or not. Then it was extremely difficult to find a good herp vet anywhere except at a zoological park. I've had to do things to my own animals in the past that you wouldn't believe because of that, such as repairing prolapsed cloacas (drawstring suture), surgically removing bound eggs from a female snake (tricky), removing subcutaneous nematodes (not a big deal, really), etc. It was no problem finding a vet that would supply you with the things you needed to treat your own animals, luckily. Once he (or she) got to know you a little, they knew that you were capable of doing it and they didn't usually have a problem with selling you the supplies, meds, etc. to do the job. It got to a point that they were calling me with husbandry questions, etc. if a client called with a problem. Once a Vet in Dothan, Alabama called me with an injured Great Horned Owl. Someone had shot it in the eye with a pellet rifle and the eye had to be removed. Then they couldn't figure out how to get it to eat or drink. I took that one home with me and rehabilitated it and was finally able to release it. It had to learn to hunt all over again because of the lack of binocular vision and depth perception.
At any rate, all this rambling is intended to say that your best bet is to settle on one Vet and form a good relationship with him. That way, he will learn more about treating reptiles (if he's not already a good herp vet)and will be willing to go the extra mile or two with you when you have problems. Be willing to help him too, if he needs it. Vets are good at treating diseases and injuries, but often have little experience with husbandry and breeding. You have a wealth of practical information here at your fingertips from a lot of people with decades of experience. If you are willing to share that with him it goes a long way.
