Un-modifying a shipping container

[ericknight]

Just bought a 40' shipping container. It was previously modified with an office in one end, complete with entry door, window, and hole for air conditioner. The window and door were crudely installed with wood and it is now rotting. I am looking for a way to cover the holes back up. Anyone know a source for the corrugated steel these containers are made from? I may keep a door in the side, is there a prehung door made with a metal frame that can be welded in?

Yes, there are steel doors with steel frames. Seems like the high school has them for some of the doors.

Having a door there would be nice. I was looking at a container but where the wife said I had to put it was a quarter mile walk from the house and not road there.
