I start with a sort at DC or more often, P41;, based upon max. price, age range, geography and occasionally services provided, although what a provider claims to do and what actually happens can be two very different things..
Then I scroll thru the pictures, taking a peek at the profiles of the women that catch my eye. An interesting or at least informative profile really, really helps. This is probably where I get most selective.
I will read any review I can get. If she has many reviews, I do not get overly concerned with the extreme scores. I've found extreme scores, on a well-reviewed provider, tend to be due to a rare or unique chemistry issue. I actually start with what appears to be average scores if I am reading them here at TER. I tend to pay more attention to actual services provided and attitude here than anything else.
If I am still interested, I will check out her website. By this time, I usually have it narrowed to one or two. Sometimes nobody. Then it is just a matter of who gets scheduled first. The "runners-up" get marked for future consideration and are usually the first ones I look at the next time I get the itch.
So far, I must say I have been very fortunate. I would recommend all of the women I've seen in my short time in the hobby.
