I do the delivery work for most of the local retailers that sell gun safes. There aren't many people who can fully support the safes they sell if they aren't true safe companies to begin with.
I would start by calling Langhoff's Lock & Safe at 678-982-0198. Tell them a fellow Clearstar member sent you.
If he doesn't work out for you, I have another guy that's about 10 miles away who does a lot of commercial work. I don't know if he deals in gun safes, but even if he doesn't, would know who does.
