Yeah, I went to three shops (one cabinet shop, one glass company that deals in plexiglass and then finally a company that does a large volume of plexiglass template cutting). I dropped off a speaker template and they are going to laser cut some brackets for me with the screw holes in them. Should be ready on Thursday. I'll post pics when I get them.
