Great idea to start now!
I don't think posting here needs its own scheduled task
Resource scheduling is very helpful, in making sure your resources (people) don't get overloaded. Unfortunately, it is difficult to capture most high school students, with any certainty.
You may be best served by working this schedule out with as many people on your team as possible, rather than asking here. After all, you need your team's buy-in. They have to work to the schedule. Be open to changes.
