When I lived in Beaumont a friend of mine and the business that I worked for bought a Fort Knox from the guy listed below. I can't remember his name but he shows up and the bigger guns shows once in a while. He is able to deliver anything you want. He is not the cheapest guy around, but if you have cash I bet he will deal some. Do your research before you go see him. He is right on I-10.

There is one guy that moves safes that lives on the northeast side of town but I cannot remember his name. I would talk to the guys at Gander up that way and they might be able to help you. I sold my safe in BMT before I moved and the guy who bought used him. It was a Liberty 35 gun safe that weighed close to 1,000 lbs and he moved it by himself. it helps to have the correct equipment. Sorry I didn't get his name.
