Advice please - how to donate money to someone for charity

[bloonoo]

Hi everyone

My friend is currently in Cambodia doing volunteer work for a kids residential centre. She is the only Occupational Therapist there and desperately needs funds to help make the place better, the kids have holes in clothes, no shoes, no toothbrushes etc etc - I am going to do an appeal over here with all my friends and work colleagues etc, but I need some way to get the money donated across to her.

I looked at JustGiving and it looks like only registered charities can do it (they're not one), and something called Yimby but it all takes a cut of the money, plus with Yimby you only get 30 days to raise the funds. Does anyone have any ideas (other than me literally giving out her account details and people transferring cash to her - which understandably I don't think people would be too happy with), that we could try? I am probably being dim and overlooking something very simple!!

Thanks
