I'm a student ambador and I need to get a grant for $1,000 who can I look for, for help?

I am a Student Ambador in the People to People program and I wanted to know if you could send me some information about getting a grant. I am currently a High School sophmore in Fairfax, VA with a 3.8 GPA. I have attended other leadership conferences and would like to add People to People to that list. The cost would be a financial hardship on my family and I'm looking for other ways to offset the cost. My next payment of 1,000 is due December 29, 2006. The total cost for my trip is $6,000 please let me know how I can get some sponsors.
