From your post it sure seems that you're very excited about making this happen... and ambition is all you need! If you are not getting answers as soon as you'd like, or the answers you want... DO NOT GIVE UP! What I learned is to stay on top of people, keep calling and emailing them... when they see that you are putting that much time and effort into this cause, they will most likely come around with a positive response. This usually works.
Just remember not to let your grades slip
GOOD LUCK!
