Writing a script for booking bus seats

The services of a web programmer are required. You need to write a script for booking bus tickets. It should be possible to output on the WordPress page of the site. Maybe even a WP plugin.
Opportunities:
Buses development
Creation of seats
Schematic display of seats on the booking page (like on a bus)
For the client:
A person lands on a specific page with a direction (we have few of them)
At the end of the page sees the booking form.
First, the date, selects the available seats, moves to payment. Payment through Liqpay.
