I remember this one, I was quite close to booking her.
I made a few email enquiries to her a couple of months ago. Comms with her were quite good and she seemed to meet my requirements. However, at the point I was about to book her she immediately increased her prices, from £250 per hour, to £300. She also had quite a few positive AW feedback roll in at around the same time too; All of which seemed quite dodgy to me. I never went ahead with the booking at that point (no way I'm paying above £250, no matter how good she is).
I did, however, keep a check on her profile for several weeks after and realised this price increase of hers was bollox. She gradually decreased her price back down to £250 per hour over a period of a month. It seems to have been at this price ever since, despite the dubious positive AW feedback rolling in too.
