We're paying our agency and another agency in the state where the birthparents live and it's not cheap either. We have to do this though since the PBM is out of state. Ironically I feel much more connected to the out of state agency staff than ours.
If you're comfortable with the agency that has the match you could just use that agency and not your own. I bet both agencies would work out a plan for you if you are chosen. Like maybe one agency does counseling and the other handles consent/relinquishment etc. Ask your agency and see what they think. GOOD LUCK with your potential match!!! How exciting!
