First of all,
THANK YOU, SIR for your service.
Who to build your gun? Like Steve said above
any of the smiths here can build you a fantastic 1911. Might I suggest that you take a look at all of the pictures posted here (as well as other forums) go to each smiths webpage and look at the pictures there and then choose one or more smith with whom to correspond directly. They will answewr your questions as well as give advice and recommendations. It's kinda like shopping for a car. Pick the style, options and "dealer" that you like, want and can afford and then go for it!
I can almost promise you this though, the first one, no matter how well planned out and executed will still not be exactly "it" and you'll have to have another, ... and another, ...... and another .......... and another.
But it's fun!
Stay safe
