Web application for a wooden canoe workshop

We build canoes from cedar strips and using wood-canvas technology by hand, and our old brochure site can't handle the load anymore. We need one web application that runs the entire workshop. The heart of the project is an order configurator. The customer chooses a hull model, then wood species (western red cedar, white cedar, decorative walnut strips), length from 12 to 18 feet, gunwale material, seat weaving, and clear or tinted epoxy finish. Each choice recalculates live price and estimated shop hours. Submitting the spec creates a build order, not an instant purchase — each hull is made one at a time. We can only lay down a few boats per season, so we need a waiting list for build slots. Confirmed orders take a numbered slot on the season calendar; the rest queue up and get a letter when a slot opens. Each active build has its own progress page: steak gathering, fairing, fiberglass gluing, gunwales, finish — with dated photos that the owner follows along. Restoration intake is a separate flow. An owner sends their old canoe with photos and description; we document condition by section (stems, ribs, planking, canvas) and reply with assessment and estimate. A photo journal stays attached to the whole restoration. The shop sells paddles, kits, plans, and materials with a standard cart and checkout. Master classes (weekend paddle-building workshops, two-week canoe course) need a calendar with place limits and deposits. The gallery shows finished canoes filtered by model and wood. Suggest a stack; we prefer PHP or Node backend with PostgreSQL and careful image handling.
