Help Needed Sexing snakes in Denver, CO

I know, I know...I have not one but two great herp vets out here that could do this for me. But since I can't drive I can't get to them, and I certainly couldn't take 8 snakes on the bus. :)

So, I was wondering if there wasn't someone in the Denver area skilled at popping/probing that could come on up and help me out? I'll be wanting to breed the corns next season and the BPs as soon as everyone is big enough, so I really want to make sure that what I have is actually what I have. :D

Oh, and I live at 85th and Pecos, right next to Water World. :)
Thanks!
