I don't know about boards, but offer the following tips: First, the vegas market is still illegal (legal brothels are many miles away in the desert), and it is very crowded as well. They look good, but don't expect to have a montreal experience. No GFE's in vegas. Although you may be able to negotiate something in a stripclub, the cost will be exorbinant. There are advertising circulars available on the street with lots of ads for agencies and sp's, these may be your best bet, but choose carefully. A cab driver may also be able to hook you up...(note that cab drivers are a good source of info, I have had one offer to set me up, as he was apparently running girls. Beware...the strip clubs pay cabbies to steer customers to strip clubs.) I would avoid any street action.
It may be possible to find a pro working a casino or casino bar. The Rio was known for this. Negotiate the price. They will try for $500. Don't pay it. $300 seemed to be the going rate for most sp's.
