Custom Leather Bicycle Saddle with Matching Handlebar Grips

I'm looking for an experienced leatherworker to rebuild the saddle on my road bike and wrap the handlebars to match. The bike currently has a stock plastic-shell saddle, and I'd like a full-grain vegetable-tanned leather top made for it — roughly 3–4mm thick before wet-forming, so the cover holds a firm shape at first but still breaks in and softens with riding over the coming weeks. Please wet-mold the panel directly over the existing saddle shell (or a form built from it) so the curve at the nose and the flare at the rear match the shell exactly rather than sitting loose. I need the cover to attach securely to the plastic shell and steel rails underneath — either a channel-and-lace method around the edge or a riveted skirt, whichever holds up better under a saddle that flexes with every pedal stroke. Please avoid glue as the sole fastening; it should be mechanically secured so it survives rain and years of use.

Alongside the saddle, I'd like a pair of hand-stitched leather grips for the handlebar — a wrapped-and-laced style rather than a slide-on sleeve, using a thinner, more supple hide (around 1.5mm) than the saddle leather so the wrap sits flat under my palms without bulk. Saddle-stitching by hand, not a sewing machine, please, since that's what will hold up to sweat and grip pressure over time. Once both pieces are stitched, I'd like them treated with a break-in conditioner or leather balm so the fibers relax and the color deepens evenly instead of patchy. A natural tan or medium chestnut color for both pieces would be ideal, and I'm fine with visible stitching and a slightly rustic look — I don't need a flawless factory finish, just something sturdy and comfortable that will age well. Turnaround of under two weeks would suit my schedule, and I can drop the bike off or just send the saddle shell and bar diameter measurements if that's easier for you.
