Bookings By Date?

Hi all!

I’m looking into creating a website for babysitters. Ideally, I’d like to add a process whereby babysitters can create their own profile and enter their hours available to work on a daily/weekly/monthly basis. When a user fills out the booking form including date and time range I would like it to automatically show only babysitters who are available at that moment. Successful completion of the booking form would then remove the babysitter from future search results for that moment.

Any suggestions greatly appreciated.
