she has made the effort to pay and get a good set of pictures better then some of the pictures around the Newcastle area.
The only thing bad with those types of professional (lightly) 'shopped photo sets is that they could be years old. I guess you could say the same about "plainer" photos (ENE, NNE, etc) but the dodgy agencies, and bait and switch types tend to use the glossy ones.
Anyway, I'm on the fence too. The half hour rate is clearly just to put guys off the short bookings. £150 would be the absolute max I'd pay for a one hour, but only for someone stunning who offers PSE, ideally with a good reputation. Doesn't Brooke Knights charge about the same?
