Since it's from a very under developed part of Africa, you can be 100% sure that you're in for big money on bribes alone, before you even see one!

It'll probably be easier to go through an agent or importer, but even then it seems like a waste of money. Is there any particular reason you want a wild caught one? If you just want a new bloodline, maybe contact a South African breeder and ask about getting a captive bred animal from here, it'll probably be cheaper and you won't have to bribe anyone, it's also better for the environment.
