Pin/Weld AR Hider in Pittsburgh

After calling almost a dozen gunshops, I finally found one in McCandless that'd remove the permanently installed flash hider on my 14.5" upper and replace it with my AAC Brakeout.

The trouble is, it's been two weeks and they haven't even touched it yet since I dropped it off. They still won't give me a time estimate or any idea of how much it will cost me once they finally get it done.

Does anybody know of any other smiths in Pittsburgh that could do the job?

whats the name of the shop? and where are they?

I don't really want to get into it just yet, while they still have my upper (3 weeks and still waiting). Don't want to jeopardize anything before I get it back into my hands.

Called today and said they had brought it to another machine shop to do the drilling and welding, and it was in pieces... makes me kind of nervous.
