I'm sorry your snake didn't make it. please be sure to report your business with this breeder to the BOI and on the feedback section here. This is ridiculous that this person is letting these snake suffer then selling them to people and putting them through hell trying to nurse diseased snakes back to health...very sad situation all the way around. Hopefully we can put a stop to it.
Sorry for your loss.
Reputable is hard to find without research.
Same is said for trusting someone to come into your house to view an animal.
If you get a funky vibe...... Move on.
