Whooooaaa, Susan, what you described is EXTREMELY RARE!!!
C., please don't think such surrogacy situations are the norm!! I was a gestational surrogate and have been very involved in the surrogacy "world" and situations like that are so very very incredibly rare, especially when all parties involved are evaluated by a professional and have legal representation & contracts.
A couple of websites you might like to visit are www.surromomsonline.com and www.allaboutsurrogacy.com. There is a local surrogacy support group on Yahoo Groups which is AWESOME called TOSS (Texas Oklahoma Surrogacy Support). I'm not sure what the site address is, but if you do a search on Yahoo Groups you'll find it. Wonderful groups of ladies, both surrogate and intended mothers.
The agency which matched me with my intended parents was Texas Surrogacy Solutions. Wendy Bauer, an infertility counselor, was my main contact but I believe she may be doing it on her own now, while TSS is still run by attorney Jim Burnett (a parent via surrogacy himself I believe). As the GS, I don't know anything about the financials but I'd love to answer any questions you might have about anything else or even just try to ease your mind that surrogates do NOT "change their minds" about the children they carry! :)
