I need to build a web for iOS and android, to use it as the app and also to use one of it's part on the website (booking part).
The idea is to have a booking system using the distances from a map to calculate costs.
For example, a customer would choose an airport for departure and another for landing, and based on the distance between them the cost is calculated. The web app must integrate a payment system.
On top of that, there must be a intranet to manage prices and to choose the airports that are available, as well as manage the bookings, trying to keep everything as clean and simple as possible.
