Affordable adoption agency for African American infant?

Hello everyone,,,I am really interested to know what agency you used for your AA adoption. My family is just beginning to pursue transracial adoption of an AA baby girl (not yet known or matched), but we have recently been told that the agency we are currently using is ridiculously expensive (about $32,000). Need a new (AFFORDABLE) agency ASAP and would love to know what ones you guys have experience with. We are in Oregon, and need to find an agency that allows gender specificity because of room constraints. We currently have 1 girl and 3 boys, so adding a 4th boy to the room is not possible. We have plenty enough room for a baby girl though, so it is a necessity that we go that route. Please help.
