Alligator snapping turtle?

I am in the military and stationed in texas. i want an alligator snapping turtle and have done the research about owning one in texas. (they are a protected species) and i can have one as long as it comes from out of state and i can prove i bought it out of state if anyone comes to investigate. i will be heading to PA in about three months and want to know if anyone knows of a place there that i can buy an alligator snapping turtle?
