How to Use Calendly with Your Sales Team

Hi, I'm running a small team of teachers, so as our number of students keeps rising (great thing of course), I'm looking for a way in which students can book a class and choose which teacher to book with, in case a preferred teacher is unavailable, the student can select from the list of teachers available for that particular time slot (if the teacher is available). Dunno if I'm clear, but can Calendly help with that? Thank you very much.

Is there a specific setting to enable round robin calender bookings. For example we have 2 sales people and want our prospect to book a time either of them have available. And depending on the time chose, the meeting will land on the correct salespersons calendar.

this doesnt make any sense...
i was hoping for a tutorial.. cause the title says how to...
