Can't I just find a baby in a dumpster like a normal person?

Finally talked to two adoption agencies that will at least entertain the idea of a single parent. However, I had NO IDEA adoption was so expensive - we're talking $40K. That's way more than IVF. I'm shocked. How in the world do normal people (not celebrities) do this?? Still going for IVF round 2, and then we'll see what happens. OY VEY
