Amazing how it got so scorched, and without touching the case! Just kidding. I hope all are doing well since the fire.
I don't know of any luthiers near Nashville, but I'm sure there are many. As for the cost, well that could get "interesting"...Depending on what you are looking for. Fully restored to like new, will cost you probably much more than it is worth. Returning it to functionality, with all its scars and stories intact will be much more affordable. It "looks" as though the scorching may not go thoroughly through the entire depth of the woods, so other than some thinness in places, and a bit of stabilization, things should work out well.
It looks as though you are correct about the head/glue joint. The heat and string tension made it lose it's mind....Personally, I love instruments that tell a story, give a glimpse into the history. Makes the songs that much sweeter. Just wait till you play Johnny Cash "Ring of fire".......epic!
