If I was to import a species that is always going to be wild caught, and is known to carry mild parasites, what medication would be an affordable way to treat this?

If I buy a fifty dollar snake, I don't want to spend hundreds of dollars making it sanitary. How much have you all paid to treat parasites through a veterinarian? I'm just getting costs figured out- it may very well turn out that I'm not willing to work with certain imported species due to the cost of dealing with a wild-caught specimen. I have never had to treat parasites, so I'm just curious. What do you suggest.
