My most expensive BP bill was about the same as yours. Except it was a rescue with a respiratory infection that needed a culture and antibiotics.
My initial exam was $60 and that's on the higher spectrum of exam prices for exotics. Your fecal exam is pretty high in my opinion too. It usually runs $10-15. I go the a vet school to get my animals treated and they tend to be more expensive than private practices. When I went to a private practice for the same treatment(minus the culture) with a different pair of rescues, it ran about $70 total including exam and antibiotics for two snakes.
