I received a promotional email this morning from Menards. Now they offer, through a third party engraving company (not mine), custom engraving of granite and corian plaques. :

Here is the Menards link: http://www.menards.com/main/e-CustomCreations.html
It looks like $30 for a solid surface 8" x 16" address/name plaque and $55 to $95 for a quartz or granite pet memorial.
I'm actually not sure how I feel about it. I was certainly shocked when I opened the email.
