Finding an Asian or Asian/Caucasian baby girl

My husband and I are just starting the research on the adoption process....my husband is German/Irish and I am Filipino. We are looking also into international adoption, but I'm interested about domestic agencies that specialize (maybe not the right word) in babies with a similar cultural mix (Asian/Caucasian). I think that looking into agencies on the West Coast may be a good start as someone mentioned....any other input/ideas?
