What the best way

I'm working on the best way to get the word out that Sean and I want to adopted. We have been told about sight like parentprofiles.com or adoptimist.com both  cost a lot every month. It just make you wonder if it is all worth it.  Part of me thinks  that is  a lot off money to put in to something that may not pay out then there the other part that is like if I don't do it I won't get a baby. So the  big question is what  is the best way to find the baby that is meant to be ours.

Then there the other side of me that not willing to 100% hard core on the search for our baby until we are 100% done with embryo adoption.
