Sponsorship to attend the 14th International Youth Leadership Conference in Prague

I am a chemical engineering student, and have received the opportunity of a life time to go to Prague and attend the 14th International Youth Leadership Conference, 22 - 27 July, 2007. Its an awesome opportunity where I will learn a lot and develop with like-minded students from all around the world. I am looking for sponsorship for flights and the conference fee. I would like to come back and become the type of leader Africa needs. Anyone willing to help or advise would be greatly appreciated.
