Jtw2: Stopped by the place today. It's Rocky Mountain Arms Inc on Sunset Place (just across Ken Pratt off of Sunset) and I spent some time chatting with the guy that was working there. Now I'm bringing my Buckmark in to get it threaded for a can.
Forgot to make verbatim notes on the sign but it basically warned that they don't have a showcase, there aren't any guns there "to look at", et cetera. You have to ring the bell to get let in. Basically, don't waste your time and theirs if you aren't serious about contracting work or, in my case, getting educated (and then contracting work).
I don't know how long it'll be to scrape up the cash, get the necessary approvals, et cetera but I'd be happy to keep you up on the quality of service (seems like a really good guy so far) and the suppressor once I get things rolling.
