Web application for a stained-glass studio — orders, shop and master class booking

Need to develop a full-featured web application for an active stained-glass studio that simultaneously sells finished products and takes orders for custom work. The core of the site is a Tiffany and traditional lead-solder stained-glass window ordering pipeline: the client sends opening measurements, style requirements and references, then receives a design mockup (scaled sketch with selected glass and profile palette) that can be approved online, sent for revision or rejected; after mockup approval, a prepayment is charged. A separate intake stream handles restoration and re-soldering of antique panels: the customer describes cracks, sagging lead and missing fragments, uploads photos from both sides and receives a condition assessment and estimate.

The shop sells finished goods: sun catchers, fired panels, lampshades and faceted sets — with actual sizes, glass type, suspension hardware and a note on custom production time. The master class module publishes lessons — Tiffany for beginners, lead soldering, fusing, mosaic — with available spots, tool kit rental and a waiting list. The materials shop sells sheet glass by square foot, profile, foil, flux, solder and patina, including custom cutting. The gallery organizes past works by technique and purpose (residential interiors, churches, restoration). Finally, a church restoration estimate form collects large projects: number of openings, protective glazing, access and scaffolding, insurance documents.

Result: responsive frontend, personal accounts with order and mockup history, admin panel for orders, restorations, catalog, classes and warehouse, online payment with prepayment and balance, notification emails and clean SEO pages. Please propose a tech stack, phases and support options.
