Asking if a feature exists - schedule like physician schedule

Hi Everyone.

Excuse my English.

I need a feature/module and I don't know if is there anything done.

I have to put some people booking themselves some meeting with some educators.

So, the guy who have to book itself can book only a short period of 10 minutes with each educator.

And, of course, it's supposed that any other guy won't be able to book anything else at the same time with the same educator.

It's a schedule just to make a pool, a line, like in the physician scheduling. You book a time, but you know you won't be attended at that time, but you have your position in a line and the physician know more about all the situation. And, of course, it's impossible to book more than one person at the same time (yeah, I know the reality is a little bit more different).

Ok, break: is there a name for this type of schedule?

Is there anything like this in Drupal?

The whole situation is more complex because the guy have to book a time related with his son and the school group of his son.

But if there is something similar, maybe I can make some changes.
