Welcome to LV FEVER
Thats a good site for independent escorts with reviews and all, found some nice ladies there.
Some useful information may also be found on the usasexguide:
Las Vegas

As nobody has mentioned it yet - you may want to keep in mind that even though its being handled quite openly there any form of paysex is illegal in Las Vegas. And depending on season (or whatever) the police will hunt for both punters and ladies.

Having said that there are loads of opportunities and you can have a great time there.
Happy punting
