I'm going to be traveling around Vietnam Cambodia, Laos, Thailand, etc from late February to Mayish.
Anyone know of any free volunteer projects looking for help?
Dont have a lot of money to spend on an agency, but have plenty of time to help.
I have friends in Phnom Penh that help orphans and poor families with: food, shelter, health care, school expenses, etc. There are no fees involved and they can always use another pair of hands.
Send me a PM if this sounds like something that might interest you.
You could try the SAGE Foundation (http://www.sagecambodia.org/). I volunteered there as a teacher for a couple of weeks about a year ago and that was great. All you have to pay for is travel to and from the school (when I was there I stayed in Seam Reap, with the school about an hours drive away, but there was talk of finding accommodation in the small town where the school is).
Failing that, just ask around when you get there. There are NGO's all over Cambodia that really need volunteers.
