I want to wish you luck. Starting a new team from scratch can be hard but I hope it works out. It's also very good that you've got support from the principal and hopefully he/she can encourage (along with you) some of the students and teachers to join.
Oh, and don't forget, when they're building this school kindly remind them that your future team would like a robotics room and possibly another room big enough for a mock field to practice on.
