drupal 9 example site with possibility to book meeting rooms and display availability using full calendar

I am looking for an experienced team to design a Drupal 9 example site with the ability to book and manage meeting rooms, as well as display their availability using a full calendar. The booking system must have basic functionality, with the display calendar implementing the standard features. Additionally, the user access must be advanced, with only registered users able to book the meeting rooms. The team should have demonstrable experience creating similar projects, preferably on Drupal 9. All project submissions must include a timeline for completion.
