Car CASCO Insurance Cost Calculator Widget Needed

We run an insurance company website and want visitors to see an instant, ballpark price for a comprehensive (CASCO) car insurance policy before they ever talk to an agent. Right now anyone interested has to call or fill out a form and wait for a manager, and a lot of that traffic just leaves the page. We need a developer to build a compact calculator widget that takes a handful of inputs — car brand and model, year of manufacture, current market value, the owner's driving experience, and which risks to cover (theft, total loss, accidental damage) — and returns an approximate policy price right on the page, no reload needed.

The pricing logic can start simple: a base rate tied to vehicle value, an adjustment for vehicle age, a discount for driving experience, and a markup per selected risk. Coefficients need to be easy to edit later without touching the front end, since underwriting revises pricing fairly often. The widget should work smoothly on desktop and mobile and be simple to embed into different pages.

What we'd like to see from applicants:
— experience building similar quote or cost calculators
— comfortable keeping pricing coefficients in an editable config
— clean, mobile-friendly interface with instant results
— willingness to walk through the calculation logic before development starts
