Custom Handmade Leather Phone or Tablet Case

I've gone through three flimsy plastic cases this year alone and I'm done buying cheap junk that cracks at the corners and turns yellow within a month. What I actually want is a case handcrafted from real leather, built specifically around the exact dimensions of my phone (or tablet, depending on what we agree works best for this project) so it hugs the device instead of adding bulk. This isn't a generic sleeve pulled off a shelf — I need someone who works with hides directly and can shape a folio or slip case that fits my exact model, cuts precisely for the camera, buttons, and charging port, and holds up to daily use in a bag or pocket.

Beyond the fit, the small details matter a lot to me. I'd like my initials tooled or embossed somewhere discreet, a color that leans toward a deep cognac or forest green rather than plain black, and visible stitching in a contrasting thread that gives the piece a hand-finished look rather than a factory one. If we go with a folio style, I want a couple of card slots built into the inside flap so I can leave my wallet at home for quick errands. I'm open to suggestions on leather type and hardware — magnetic closure, snap, or none at all — as long as the final piece feels solid and ages gracefully over the years.

What I'm looking for from the maker:
— Confirmation of the exact device model and dimensions before any cutting begins
— Full-grain or vegetable-tanned leather, no bonded or faux leather
— Personalized initials or monogram placement I can approve beforehand
— Clean, even contrast stitching and precise cutouts for ports, buttons, and camera
— At least two card slots if a folio style is chosen
— Progress photos at each stage before the final piece ships
