I believe if you start talking vet you would be looking at $100-$200, nothing at a vet is cheap.
it's really not that hard to do yourself, a little nerve wracking the first time or two but not bad after that. I used to have to trim my south american puffers teeth every 3 months like clockwork, first time I put them out, after that i did not, they cooperated well and it got easier and easier. cuticle trimmer and away you go.
I have some scaley and a few not so scaley creatures living in glass houses full of water in the other room
