Who would you go to for a high end saber based on the Jedi Temple Guard?

I am looking for a double ended Jedi Temple Guard Saber, I have attempted to contact Vader's Vault to no avail and Genesis does not I think do sabers based on actual characters.

Who would you go to get a saber that is

Brass/Aluminum Construction
Duel-able
Has a high end sound board
And can be decoupled

Any assistance or pointers towards a smith would be great!
