hi jarvman

if you can't find anyone in your neck of the woods
you might look into contacting http://www.portfoliobox.com here in the states.
they do amazing work, all custom, boxes books, leather, cloth, dust cases ... you name it!
i 've had them make 5 custom books for me over the years, never a box though. i DO know people
they have made boxes for, and nothing but good words ...

good luck!
