Justin - Thanks for your service!
There are a lot of very skilled individuals here on the site. Somebody here has most likely done it, seen it or helped do it for somebody else.
My suggestion would be to throw your initial thoughts/questions out and let the discussion/ideas begin.
For example: Are you 100% set on a metal building? Do you plan on having it built or building yourself? Will it be a dual purpose structure (ie living quarters and shop/garage/etc)?
Are you thinking of a pole barn (wood skeleton) with metal siding or complete metal structure? What are you thinking of in terms of heat/cooling?
These are just some starters. Plenty more questions out there. Welcome to the site and thanks again.
