Help me get to Sri Lanka to be a volunteer

Hi, I am a young student from Budapest. Before going to University I told my parents, If i will not get admitted to the University, I will hitchike around the world, learning about other cultures and help people where I can. Fortunately, I got my admission, so I am a student now. However, I decided that in my summer break I will go on volunteering and learn about another culture. So I'm going to Sri Lanka and I will help people by volunteering. As a student I don't have the time to go hitchhiking, so I will need to fly there. The travelling costs are really expensive, so I would like to ask for your help, to get me to Sri Lanka.

Any donation will be greatly appreciated. Thank you very much!
