I think that Squirrel hit the nail on the head with his third point that the prices are out of line with the economy. As for myself once you go above $150 (or $200 for the hour), you are talking about a part of a mortage payment, and it is not a hobby anymore (remember we are only renting the product and not buying). Since most of the sp's with good reviews do not have half hour rates, this limits the op's to play. Second, if you do find a jewel in the rough if you post about her then two things happen:
1) you can't book time
2) somebody f's it up by telling her that she should have higher prices, which go up soon afterwards
So I only post when I have bad service. If it is medium, I don't want to be flamed, and if it is good, I keep it to myself (sorry guys).
Julia, you might say that I am a "Frugal John" (perhaps I should start a website), but I think that good service should be able to be found at the $150 mark consitently. At that mark it is easy for a woman to make over 10k a month.
