On the subject of price it seems it isn't always cheaper the better though, there was a well known girl on PP who asked about what people thought of her putting her rates up from £100 to £125.
A lot told her she'd lose a lot of trade but she tried it and later reported that she actually saw far more punters when she did as well as earned more per punter. If I remember rightly she said it was because a lot of punters wouldn't book her at £100 because they thought that it was too cheap so wouldn't even consider her, I can't remember who it was but sure one of the other PP members might
I never said cheaper equals better anymore than expensive does, that in reality depends on the WGs attitude not what she happens to charge, good WGs are good at whatever they charge and bad at whatever they charge.
What you mention here relies on punters taking her word for it though of course which may or may not be true.
There is a view held by some punters that sub-£100 an hour WGs must be bad or there is a catch, this isnt necessarily the case as i and other punters i know, trust and/or respect know from personal experiences. As ever it depends on the individual WG.
An EE WG coming here is sometimes prepared to start in London at least at £60-100 an hour to get initial business and once established might put her rates up. Also some others are here for a fixed time and want to earn as much as they can while here and see charging low rates as the way to get the most they can. For some from a poor EE country this is very good money.
