Africa- where to get funds?

[sarki08]

hi, In about 3 weeks time i'm goin out to Kenya to visit a friend who's working and living out there at the moment. She is a qualified field guide and her boyfriend works at one of the game lodges. Anyway, down the road from where she is living, there is a orphanage home to around 32 children all aged from 3-14 years old and either have HIV or have been affected by it in someway. My friend has come up with the brilliant idea of taking them away for the weekend to the game lodge to teach them about the bush and show them the animal's which i'm sure they'll love. Only problem is, there's a slight lack of money. Anyone got any ideas of who i can contact to help fund for this and possibly, to improve things in the orphanage?
thanks
