Online Car Repair Cost Calculator

I’m looking to have a web-based calculator that lets a user pick any major car brand and immediately see an accurate total repair cost estimate. The tool must run in the browser (desktop and mobile responsive), load quickly, and return a single clear figure—no partial or line-item breakdowns, just the full projected amount.

Core expectations
• The user selects make, model, year (covering all major brands) and the type of repair.
• Behind the scenes the calculator pulls the relevant parts pricing and labour rates, sums them, and displays one consolidated number.
• I need a simple admin area or easily editable data source (CSV, Google Sheet, or similar) so I can update prices myself without touching code.
• Results should be shareable (unique URL or copy link) and printable.
• Clean, modern interface that can be embedded in an existing website or hosted stand-alone.

Deliverables
1. Fully functional online calculator (HTML/CSS/JS or preferred modern framework).
2. Documentation covering setup, data updates, and basic styling tweaks.
3. Brief hand-off meeting or video walkthrough to ensure I can maintain the tool.

Acceptance criteria
– Selecting any mainstream brand populates correctly.
– Returned estimate matches sample data I’ll provide (±2 %).
– All fields work on desktop, tablet, and phone.
– Editable price table requires no code changes.

If you have previous experience building cost estimators or similar configurators, feel free to mention it along with a quick outline of the tech stack you’d use and a timeline. Looking forward to seeing what you can build.
