Who lives in No. VA and knows how to pop?

I have decided that I need to learn how to pop snakes. I was thinking it wouldn't be necessary until we start breeding and needing to be able to identify the hatchlings. But now I'm in the market for males to pair with the females we bought last year, and find myself worrying about what if the females were incorrectly sexed and we don't find out until we try to breed them and realize we have all males. So at the very least, I'd like to have someone pop the ones we have and verify their sex for us.

Anyone in NoVA or the general vicinity who would be willing to let me come over and learn to pop their animals so I'd get experience with both males & females, please let me know! Or if you'd rather just double check my snakes for me that would be better than nothing. I have a BP and a corn, so someone who has both would be best, but beggars can't be choosers. :)
