There's a book called Understanding Reptile Parasites that is good if you want to learn how to do your own fecals, as well as recommending drug dosages. My advice on a microscope is don't buy a super cheap one. I got one for $100, and it is a piece of crap. I basically can't use it. I don't know how available the other supplies you'd need, stains, etc., would be where you are. But they must use them for dogs/cats.
