I'd say probably most gunsmiths would have the means to do this. I don't know much about your area so I can't help you there. Surely someone on here would know where to start looking.
I saw these, but I just figured it would be easier to just bore out one I had already for an AR. I found someone with a drill press so if I fudge it up this will be my plan B, thanks!
Have you checked to make sure it threads on your 9mm? I thought the 5.56 and 9mm flash hiders were threaded differently to prevent someone from putting a 5.56 on a 9mm.
