I put an ad on AAS, one hour later I had my first set of IP's email me. I called them right than. We signed contracts 2 months later. Transfered 5 months later.
My second set of IP's went to the same RE as my first set. While I was visiting my surrosons I told me former IP's that I was going to start searching my my next couple. They informed me that the Dr. had called them to ask where they had found me.
The dr had a few couples that were looking for a surrogate. I told them to give my contact info to the dr.
Spoke to my second set of IP's the next month. We signed contracts a few months later and transfered 5 months later.
