Saw the nice article about Nikki Avalon in Playboy and shortly after was invited to Vegas with some friends. Remembering the article, I started researching options through TER. I have found and contacted several ladies that appeal to me. Anyway, I am a substitute teacher right now and am working on getting my non-traditional license for second career professionals. I am a single (recently widowed) father of an adopted 7 yr old girl from China that can't take a chance on being picked up by vice from a risky provider. Any advice on getting verified with essentially part time employment?

Plenty of them out there.  The ones that you find that are common are Date Check and Preferred 411 for the indies that use them here.  The one that I used that was more common in Chicagoland is Room Service 2000.

As long as your employer is legit, not LE, and can verify that you work there.

To your main concern, if the risk of getting caught is so great that you really can't chance it, you shouldn't try.  As a client, it's a misdemeanor offense.  If they determine that you're with someone underaged or can be tagged as a pimp or driver, it turns into a felony offense.

The other option that may make sense for you is to use the legal brothels in Nye County (or elsewhere in NV).  At least the risk of arrest for exchanging money for sex is nil.  There are no legal brothels in Clark County where Las Vegas is located.  From the strip, it's about an hour drive (maybe more depending on traffic) to Pahrump where the Chicken Ranch and Sheri's are next to.  The other ones in Nye take a bit longer to get to.

In any case, if you decide to find someone closer to the strip, act as a gentlemen and treat women with respect.  I doubt any well reviewed provider will cause you harm.
