I agree with your viewpoint however my opinion is that the prices is not reasonable. the dilemma here is not that it is out of budget but rather is it worth the budget?
As we all know a WG can charge whatever her clients are willing to spend. Having seen HTF last year before she put her prices up I felt - in hindsight comparing to other sp's in the area, that she was frankly a little overpriced then. However at that point her published "likes" list was quite vanilla and most of the more "exotic" services which are now on offer were not listed as extras even. She later clarified that they were available you just had to ask.
She then changed her profile to add the extra services but then bumped her hourly rate to it's current level.
My personal view is that I can get the same services elsewhere for less so can't justify that rate. The current service list at her old price would have made her a regular for sure as I'm quite local.
But back to my original point - clearly she has clients willing to pay her premium prices so good luck to her.
