Vehicle Relocation Quote System

I need a straightforward web-based tool that instantly produces relocation quotes from any pick-up street address to any delivery street address (ZIP to ZIP). The calculator must combine real-time mileage and estimated driving time with my custom rate table.

Scope and key rules
• Vehicle types: cars and trucks, each with its own per-mile and per-hour rate.
• Owner ride-along: an optional surcharge when the customer rides in the cab.
• Trailers: if a vehicle is towing a trailer, add a size-based fee (small / medium / large tiers).
• Mileage data: pull distance via Google Maps, Mapbox, or a comparable API.
• Time component: multiply drive hours by my hourly rate; combine with mileage and surcharges for a single total.
• Output: clear price breakdown plus an all-inclusive grand total.

Deliverables
1. Functional prototype (web page or lightweight app) with an intuitive form: pickup address, drop-off address, vehicle type, trailer size, owner ride-along toggle.
2. Config file or admin panel where I can edit rates for cars, trucks, trailer sizes, and ride-along.
3. Clean, well-commented code (preferably JavaScript/Node or Python) and brief setup notes so I can host it myself.

Accuracy, clarity, and easy rate maintenance matter most. If you have questions about edge cases—oversize trailers, multi-day trips, etc.—let’s discuss them early so we can lock the logic before coding.
