That might be a typo and should be £140/hr. Before the old profile closed down, she (well whoever runs the profile) had been trying different pricing, was at 80/150 at one point, but quickly dropped back down. Last I saw her profile in Edinburgh was 70hh and either 120 or 130 for the hour.
Maybe getting too many complaints about the new prices, so started a new profile. Only need to fool some of the people, some of the time.
