Um... I know breedable females are only about a 100...
You would need the paper work on the fire, and those are going a bit cheaper as hatchlings, but a male can breed when he is about a year old, perhaps less...
Mojaves produce BEL's, so a breeding pair would be worth more than a fire and three breedable females..
BUT.. that is my opinion. You can do some simple searching on Kingsnake . com
