I sorry but if the $20.00 in price is that big you can not afford to keep any reptiles. You seem to have money for finishing a shed,heater,a/c,ect.
I'm glad you have found reptiles and you like them, but you have not even read about them at all. In everybody's special way we are saying
your only 13 time is on your side. Do lots of reading find what really interest you and come back so we can give you some help with your questions. Building a wagon before you have invented the wheel, you don't go far.
