Have you been in communication with your Regional Director? If not, she can be a big help. I'm assuming that you are in McKeesport PA** so your Regional Director is Patricia DePra.
Looking at your presentation, I see you are getting assistance from 1708 - great team and group of people, as I'm sure you now. They will be a big help.
I think you need some reasons in your presentation as to WHY your school should start a team. What benefits are there to the school and students? What value are they getting for their money? The video you plan to show will be a big help to show the excitement and benefits of FIRST, but administrators still like to see facts and figures.
FIRST has a good section on Marketing tools on their site:
http://www.usfirst.org/roboticsprogr...s-scholarships
You can get presentations and pictures there, free for your use to download and modify. They have a lot of good facts and figures on the impact FIRST has on students, and not just on potential scholarships but also on academic success, careers, life skills. It's not the same as funding a football team.
Are you going to discuss costs? And how you plan to raise the money? They may ask you about that as well.
Good luck! Hopefully I'll see you at the Pittsburgh Regional this year!
