Multi-Service Travel Booking Site

I’m looking for a straightforward travel-booking website that focuses on three core services: flights, hotels, and car rentals. Visitors should be able to enter their trip details, see real-time options from multiple providers, compare prices side-by-side, and click through to complete the booking on the partner site.

Scope at a glance
• Clean, responsive front-end with a single unified search form.
• Results page that lists available flights, hotels, and cars separately, highlighting the lowest price for each provider.
• Simple comparison logic—no need for complex filters beyond date, destination, and guest/passenger count.
• Provider data can come from public affiliate or meta-search APIs (Skyscanner, Amadeus, or similar); I’ll supply keys where needed.
• Basic admin area or config file where I can add or swap API credentials later.

I don’t need a custom design system—just a lightweight theme that looks modern on mobile and desktop. A short hand-off guide (how to change API keys, edit titles, and update styling) will finish the job.

If you’ve built booking or price-comparison sites before, please mention the stack you used and link a sample.
