Seems to be doing a semi common thing of not putting a price on the profile and then quoting different rates to different people. £250 per hour for the better TS' seems to be becoming the norm, and I really am considering seeing Valentina if Sofia really is MIA, but £300 an hour is just not something I want to swing.
Or perhaps she just really has put her rates up, in which case sayonara Valentina, and if this is a trend, possibly sayonara altogether!
