Instant Estimate Request

A sturdy, hi-vis estimate request panel for a general contractor. Visitors pick a project type, tick the scope items they need, enter square footage, drag a finish level slider from Builder-grade to Luxury, and choose a timeline — and a live ballpark price range updates on every change with a project-size readout.

The right rail collects contact details with real labels, inline validation and focus styles. The Request detailed quote button checks for a valid name, email and phone before flipping into a confirmation state that quotes the current range and a follow-up window. Everything is vanilla JS — no libraries, no network.

The look leans rugged: steel header with a diagonal hazard stripe, concrete background, chunky bold display headings and a single hi-vis yellow CTA used sparingly.

Illustrative UI only — estimates are not binding and not a real construction quote.
