Update my Joomla-Plugin to Joomla 4.0/PHP 8.

I have a small Joomla plugin that worked with Joomla 3.x. https://github.com/Theophilix/event-table-edit. Check how it works on demo.eventtableedit.com. But with Joomla 4.0 / PHP 8 so many changes have come that I need to rebuild my plugin. I don't have time to do this, so I need an experienced Joomla programmer to accomplish this task.
