Looking for recommendations from all of you experts

I recently purchased a very well built wooden storage container for use as a smokehouse on my property. The container is 7' tall, 5' wide, 8' long with a door on end that is the full size of the end (7' tall x 5" wide, I realize probably not optimal). It is about as airtight as you can get at the moment.

I plan to put concrete pavers on the wooden floor on the door end with a fire pit/box on it.

Looking for suggestions, best practices, on optimal type of fire pit/box, venting suggestions, etc for the described makeshift smokehouse.

Thanks for any/all comments, suggestions, recommendations, etc. If I'm a moron for trying to use this as a smokehouse, say that too (gently, lol).
