Antique Wall Regulator Clock Restoration

I have inherited a large wall-mounted precision regulator clock — the type with a weight-driven movement, a long pendulum, and a glass door case — that has been sitting silent in storage for close to fifteen years. The wooden case still shows its original veneer, though the finish has dulled and the glass door hinge is loose. What I need is a specialist who can restore the mechanism to accurate running order, not just clean it cosmetically.

The scope: full disassembly of the weight-driven movement, ultrasonic cleaning of every wheel, pinion, and arbor, inspection of the pallets and escapement for wear, and replacement of any bushings that have become oval from decades of use. Instead of a mainspring there are cable-driven weights — I need new suspension cables and a check of the pulley wheels. The escapement itself is a deadbeat type, and I'd like it adjusted for a beat error close to zero.

Beyond the movement, the pendulum rod needs to be checked for straightness, and its bob calibrated so the clock keeps observatory-grade accuracy — a regulator is supposed to gain or lose no more than a few seconds a week, and right now it doesn't run at all. The glass door case needs the door releveled, the hinge resecured, and the dial (painted, not enamel) gently cleaned without disturbing the numerals.

Finally, once reassembled, the case needs to be rehung and leveled on the wall, with the pendulum's beat adjusted by ear or an electronic timing device until it ticks evenly. I'd like photos documenting each disassembly stage, a written report on parts replaced, and a two-week trial period where you check back on the rate and fine-tune it. Please describe your experience with weight-driven wall regulators specifically — not spring-driven mantel clocks or cuckoo mechanisms. Timeline flexibility is fine, but I'd like it finished within the stated period.
