Adoption again??

My husband and I are just coming up on our finalization of our Lo. She is perfect and everything i could of asked for. We adopted through a agency that was recomended by a friend. We have both agreed in the future we would adopt once more, but the second time we will adopt through Foster/A child already born, and my husband wants a boy 6-7 and under. I would like to go ahead and be prepared and get the home work done. SO maybe in a year we will begin looking for a Match. I have already gone through our County the first time we were adopting. That didnt work out too well. We did the classes ect, and from the beginning said we wanted to Adopt. When it was time for them to come and do the Home study, the Lady Called and Said, "So you want to adopt and not foster, well our goal is to reunite kids, so we dont need people like you, well will call you back otherwise" Well it has been almost a year since that call. So the Question is, what are the other ways to adopt children already available to adopt. with out going through your county DEFAX. Are there agencies or something?? Oh I am in GA.
