Help me fund my South Africa internship

I am trying to raise money to go and do an internship in South Africa for 4 weeks, this experience will be invaluable to my studies and to help me further my career. I will be working with anything from children in abusive families, to drug addicts and rehabilitation or working in a prison which is something I have always wanted to do! This is a once in a lifetime opportunity for me and this is all self funded and any amount given would be appreciated immensely!
