I can't remember if you said where you were, PA? Sometimes you can find a small vet to do fecals who doesn't necessarily do reptiles. The livestock vets are a very good option for this, if you cam find one to do a smear, or a smear and a float. I remember you taking about horses, and maybe you could find a rural livestock vet. I can give you some good advice and assistance treating them yourself, if you can get a definitive answer as to what parasites your treating. The tests are pretty much the same, as is identifying the parasites, so really any vet can do that.
The other option is to learn to do this yourself. This is a very good book. I would recommend buying a used copy from amazon and reading it either way.
And this is a good site with info on how to do this yourself, as well as selling allot of the supplies.
