Agencies for Single Men

Can someone PM me with agencies licensed in Ga that deal with single Men? Another poster's comment in the procrastination thread made me think that I should look into it. While I will probably go with a foster care system adoption, I really want a younger child of about four...which can be hard to find in the foster system and even harder for a single man to be selected for. I want to find out all possible options. David PS. I chose the age four because it's an age that you can send to programs like Headstart and still allows for plenty of time to grow together.
