Welcome to the forum, and welcome back to the hobby. You should be able to find the perfect pied for yourself and your daughter. Only suggestions I can think of are to bring hand sanitizer and ask the breeder you end up buying from a bunch of questions. Whenever I've purchased ball pythons I prefer to only get animals that have readily taken frozen thaw, as it was well worth it to me to help avoid headaches of going and getting live food.
Regarding keeping the feeders in the freezer, paper bags make it far less off putting for those who aren't particularly happy about sharing freezer space.
