The Crossroads of the Aether
At times like these I try to make my way to my local Tandy Leather store and ask the kind folk there whom they know who could be of such service.
They frequently know every leather worker in the area, and each of their specialties.
I know it's not a direct answer, but short of DIY instructions, it may, at the least, be a direction you may pursue.
It's a lead and I appreciate the help.
The Professor offers good advice. I am sure that you know there is a Tandy store in Chelmsford.
Leather working is not as difficult as it might appear.
If you decide to DIY, you might find the Empire Leather Group to be a good resource.
Maybe you could post some photos.
Too bad you are not in the Houston area. My leather sewing machine is a lot faster than a sewing awl . . .
All the Best,
