I have a lot of advice, but no time!!!!!
Make sure you talk about all the scholarship opportunities thru FIRST-$4.5 million last year.
There is a whole section on the FIRST site with advice for approaching a corporation for sponsorship.
Be sure to follow up tomorrow or Friday with all the things you forgot to do. Send a written personalized thank you. If you don't have a brochure, make one quick. Write a professional letter adding important stuff you forgot. Ask if you can bring the robot back for a demo (if you didn't do this already.) Be sure to let the company know all the places you will be doing demo's. Fairs? Schools? Other companies? where your sponsor's names will be seen.
Good luck!
