Car Diagnostic Booking Website

I need a clean, responsive website that lets customers book scheduled appointment slots for their car-diagnostic service in just a few clicks. The flow should be simple: choose an available date and time, enter vehicle details and contact information, then pay deposit securely with a credit or debit card—no account creation or login screens anywhere in the process.

Core requirements
• Calendar-based booking module that shows only my pre-defined inspection slots and prevents double-bookings in real time.
• Stripe (or another reliable gateway) fully integrated for card payments, with successful-payment confirmation sent to both the customer and me.
• Lightweight admin area where I can add, move or cancel slots, update pricing, and download booking reports.
• Mobile-first layout so customers can reserve a slot from their phone at the roadside if needed.
• Automatic email and SMS reminders 24 h before the appointment to cut down on no-shows.

Acceptance criteria
1. A user can land on the site, pick a slot, pay, and receive a confirmation in under two minutes.
2. Payments settle to my business account and each successful charge appears against the matching booking in the admin panel.
3. The system blocks overlapping bookings and reflects any changes I make in the backend instantly on the public calendar.

Deliver the finished site ready to deploy on my existing hosting, along with brief instructions so I can manage slots and view transactions myself.
