What am I doing wrong?

Speaking as a client of escorts, £150 per hour is pretty much my upper limit, and I'd usually only pay that much for a well-established escort with an excellent reputation, or one who really stands out from the crowd in some way.

It sounds to me as if you're pricing yourself out of the market. A typical price for a newbie would be closer to £100-£120 per hour, depending on various factors. At least around here (the southwest), but I imagine it would be similar in most places outside London.

Use your price as a means of controlling demand. Generally speaking, the less you charge, the more money you will make (within reason), but obviously you'll be making less per booking and putting more hours in.
