PHP Event Calendar using MYSQL and drag/drop event updating

I need a developer to create a PHP based calendar/booking system which is populated with data from a MYSQL database. (There is no table as yet).

Structure would be
Left hand column the title of the event
Across the top times of the day from 7am to 11pm (customisable)
Calendar to support dragging an entry from one cell to another and updating the database
I have included an attached image as an example of the sort of display required.

The default display would the display all events for the current day, colour coded for categorising.

Each event in the DB would store, (Event Name, Event Type, Start DateTime, End DateTime, Category colour)
When an event is dragged for the current day it would update the database with the new timings.

There is a configuration table which holds the Event Name and Category colour. Adding a new event needs to be able to select for the current day or a number of occurences based on Number days, re-occuring week.

The current framework is planned on Bootstrap 4, Mysql and PHP.
