Comprehensive Travel Booking Application Development

I want to build a travel booking app with a design and user experience similar to Skyscanner.

The main idea is to have one app where users can search and book:

* Flights — domestic and international
* Hotels
* Ground transportation — bus, minibus, taxi, private car with driver, etc. (not car rental)

The flight section should have the same type of experience as Skyscanner: simple search, flight comparison, filters, sorting, flight details, prices and booking.

The hotel section should allow users to search, compare and book hotels with photos, prices, ratings, rooms and reviews.

The ground transportation section should allow users to search routes, compare available transportation, see prices and schedules, select seats and book their trip.

I want the overall UI/UX to be modern, clean and easy to use, with a similar feel and simplicity to Skyscanner, but with our own branding and design.

The app will be built with Flutter for both Android and iOS, with API integrations for flights, hotels and transportation.

I’m looking for someone who has experience building travel, booking or marketplace apps and can create both the frontend and the necessary backend/API integration.

Please send examples of similar work, estimated timeline and price.
