profile of clients.  If you know them by name it is not difficult to contact them to  try and  reestablish the relationship, it is the bookers not the K-dolls who give references.

Some  of the old numbers you may have  used could still be active and the agencies who own them are still with the same bookers but other # may be diconcted or are manned by different bookers.

It would help if you have the same TER handle and your reviews are still up.

There are several bookers who take references from reputable independent providers and others who would work with you on an alternative screening system to the standard one. Politeness , persistence and perseverance pays off.

Good Luck.
