Dear CLIENTS.
Since it is your good self's that avail most frequently of escort services I felt that you are the best at offering advice in the following.
Am seriously considering charging clients via a premium rate no.in order to get rid of time wasters and nuisance calls.
In addition, I am considering setting up a pay pal account where genuine clients can pay a deposit fee in order to make a booking, which will be deducted from the overall charge.
I feel its unfair to both I and prospective clients where you work on a first come basis. Time is of the essence for both parties.
Any thought's.??
Slan.
