What Now?

I'm struggling trying to figure out new ways to get the word out that we are adopting.  We have pass along cards, we've posted on Facebook, my button is on numerous blogs.  And yet......nothing.  I went to post again on Facebook this morning and it just didn't feel right, so I deleted my post.  I need some new ways to let people know.  If I had tons of money, I'd rent a billboard along I-15 and post there. :)  It's time to start thinking outside the box.  I have to get the word out!  I want our birth mom to be able to find us.  I just keep thinking there is a little girl out there waiting for us to find her.  How???  What now?
