I am getting back in the hobby after a while.  I hardly see the rates specified on provider's ads -- not even as euphemism, especially for K-girls!    

Has the scene changed where you have to negotiate services and rates after you meet a provider? What's the 30 / 60 min avg rate for K-girls now a days?

I look at Tryst, mostly, and most of the time, rates are specified on the ad OR she has a website with the info.   I can't comment on K-girls.

Most of the K-Girls sites/ads don't list prices anymore, the PO will tell you the price when you book along with any extra charges.  

These days different girls at the same house can have different prices, services, and upcharges for extras (but they generally all start in the $300/hr range). Extras in K-girl land means BBFS usually, sometimes MSOG but that's usually not an upcharge.
