+1 to Phil
I tried to see you on the 8th and you did not get back to me until the 12th. That told me you were very busy and I just wrote you off as someone who was too popular to see.
As far as your rate @ $300/hr you are not out of the ballpark. The 1 bad review does not kill your reputation. You do need to understand that at and above $300/hr a certain level of professionalism is expected. You have to always look good and bring your A+ game to sessions.
There are ladies who do are not close to you in the looks department but are very busy @ $150 - $250 because they bring that A+ game every time. The best session I ever had was with a UTR lady who charged $500/hr. She spent about an hour pre-session getting to know me via email/text. She then knew exactly what I wanted and let me tell you ... I was hooked. Then she went and got engaged...
Plus I noticed you raised your rates on P411... best wishes but from what I have seen there are very few ladies who can do that and be successful. It is best to start high and run specials. Girls at the $500/hr for a special rate need to have your tits but be very tone and what they don't admit out here is they are all TOTAL SLUTS BCD. I mean they give A+++ porn star, I am going to fuck your brains out performances once they get BCD. They are ladies out in public at dinner but once the session starts they go into TOTAL SLUT MODE. I have read several of your reviews and there is potential but you are not there yet.
Plus at that rate you need better communication. It should never take more than 24 hours to respond to a session request. You may want to look into hiring a scheduler. There are several high end girls who use one. You don't need your own, just find a good one that someone else uses and see if she has room for one more girl. If you are going to do it yourself remember it is a job and treat it like such. If I waited that long to call a client back I would be out of business. Even if I just call them back and say I cannot get to their issue for a day or two I still call them.
I hope I have not been preachy. I meant this as a way to help you figure out where to go from here. If I was not already booked for the next 2 weeks I would see you.
Best Wishes and remember if you don't enjoy what you do STOP and go do what you love.
