I suggest, you get out the yellow pages, funeral homes, and go down the list, all local numbers, doesn't cost anything.
It's an eye opener, tell you right now.
One suggestion, in case this hasn't been made, is to have a list (or a search capability) of funeral homes on the eternalimage.net site that carries the EI products. The PR says to call EI to find a local funeral home, but shouldn't that also be available online? That way each funeral home could also see what their competitors are doing and follow suit.
