Why, is the baby going to eat them? As long as you wash your hands between handling the snakes and your daughter, she is not at risk from a pair of BPs. However, if you're intent on selling them, you should check out prices on Kingsnake.com and Faunaclassifieds.com. You may have difficulty selling them as hets without paperwork from the original breeder, unless you have a reputation built that can back them (not saying you don't, I just don't know you).
