Hi,
I am currently working with Seminole County. I have a child as a pre-adoptive placement right now. I worked with Orange county first so I have been given a new number for Orange county since they are going private I don't know if it will help you or not. 407-398-7975. Also you may want to contact One Church One Child they recruit people to adopt.
