reviews / girls can be found at
www.sfredbook.com (redirected to myredbook.com I think these days).
First off, the "average" date in Vegas/Reno will set you back about $300. Plenty of girls that do BBBJ, DFK, FS in that range. But if you want Greek or CIM or something along those lines, expect to pay more, as in closer to $400 and at worst up to $500. Yes, you can (and I have) found ladies cheaper than that and have gotten some pretty good service but that's few and far between. You 100% absolutely want to avoid the brothels (starting price is $500 for 30 minutes, one pop, EVERYTHING including her is covered) and never call the girls on the flyers that you find on the street. The $49 listed there is just for her to show up and it's a hardcore upsell and most often a bait & switch.
Backpage is also equally unreliable there if not for the whole of the US. There are rare gems there but cities like Vegas, San Fran, LA, NYC, Miami, etc are notoriously bad for finding women and even getting you ripped off (or worse, robbed). So stick with sfredbook.com, you can find the occasional deal on there but Vegas is all about money and with the brothels charging so much for legal pussy and the volume of gambling going on, those girls not working in the brothel naturally bring up their own prices. If you do your homework you can find something real good but it's not gonna be on your first look into things.
