Rube, you are so right!
I'm sure if they would have put in a search, they could find someone willing to work for them that knows how to make lye soap. And, yes ingredients are cheap. Marrow and ash? I just pd $1.00/lb. for beef bones at the meat market. For a few dollars I made a boatload of beef broth. If I was making soap, I think I could get quite a lot of marrow out of 30 lbs. of bones. I really don't think it's the cost or lack of a soap maker they are considering.
