Best off replacing the 55G with a cage that will last it through early adult stages rather than raise the existing cage. Are you decent with simple hammer and nails? Lumber stores can cut wood for you to make a more effective habbitat.
Doc Stacey who a few of us on here know I think is more specialized in avian but she is awesome with scaled friends.. suggestion for avian vet is a great one.
Herpvetconnection.com and arav.org have exotics vets listed but both sites are terribly out of date... but they might just have a better vet listed for ya.
