Custom Hand-Stitched Leather Wallet with Personalized Monogram

I am looking to commission a fully hand-stitched leather wallet (or a small crossbody bag, open to either depending on your recommendation) as a one-of-a-kind piece rather than something bought off a shelf. I have been researching traditional saddle stitching and want a craftsperson who works entirely by hand, not with a sewing machine, because I care about the visible texture and durability that comes from that technique. This will likely become an everyday item I carry for years, so I want it built to last and to age well.

For materials, I am leaning toward full-grain vegetable-tanned leather in a warm chestnut or dark cognac tone, though I am open to your professional opinion if another hide would hold stitching and color better over time. The piece needs a monogram or small personalized stamping — my initials, or possibly a short custom mark I will provide — placed subtly on the interior or a corner rather than shouting for attention. I would like to see a sketch or mockup of the monogram placement before any cutting begins.

I do not need rush delivery, but I would like regular progress photos throughout the process — cutting, dyeing, stitching, edge finishing — so I can follow along and request small adjustments early rather than after the piece is finished. Please share examples of your previous hand-stitched work, particularly anything showing saddle stitching and personalized stamping, along with your quote and estimated timeline before we begin.

What I need:
— Fully hand-stitched (saddle stitch) construction, no machine sewing
— Full-grain or vegetable-tanned leather, color to be discussed
— Custom monogram or initials stamped/embossed in a chosen spot
— Progress photos at each major stage
— A firm quote and timeline before work starts
— Portfolio examples of similar completed pieces
