Your prices are going to be much higher in LV because that's where the disposable income goes to get blown in oh so many ways.  People like me save all their extra cash to play in LV.  That drives up the prices even though there is such a huge playground and playmates to choose from.  Sure you can find ladies in the $200 price range most of them hang out on the strip at night or the lower end casino bars.  At $350 and up you will enter a whole new world.  Do your homework and you can find some great values.  And it's not exactly the more you spend the better the lady.  But there is a bigger variety of  better experiences to be had in the higher price ranges.  Most TER ladies charge more because frankly they are worth more and they are dependable.  There are also a few $350 ladies out there that provide a great experience at a great rate.
