Car Rental Website Build

I need a fully-responsive website that presents my car rental brand in a clean, corporate and professional style. The site should guide visitors smoothly from browsing vehicles to completing a paid reservation without leaving the page or switching platforms.

Core flow
• Visitors browse cars, filter by category or date and instantly see availability.
• They choose pickup and drop-off locations, review pricing, and secure the booking in one streamlined checkout.
• On my side, an admin panel lets me add or retire vehicles, adjust rates, and monitor every reservation in real time.

To make that happen, the booking engine must include:
- Real-time availability checks
- Automatic booking-confirmation notifications (email and/or SMS)
- Pickup and drop-off location selection

For payments, I want the checkout to accept:
- Credit/Debit cards
- PayPal
- Bank transfers
- Nowpayment

A dashboard with role-based access is essential so staff can update inventory, block dates for maintenance, or issue refunds without touching code. The interface should look equally sharp on desktop, tablet, and mobile, and load quickly even on slower connections.

Please outline the tech stack you recommend (for example, Laravel, React, WordPress with custom plugins, or another robust combination) along with a rough timeline for:
1. Design mock-ups
2. Booking system integration
3. Payment gateway configuration
4. Admin panel build
5. Final QA and launch

I’m ready to move forward as soon as we align on the approach and milestones.
