Volunteering in Cambodia

Hi I am working in Dublin but really keen to travel to Cambodia and volunteer for approx 2 weeks, I am a teacher in Dublin and I am wondering if anyone knows of any Irish or English charities working in Cambodia that may be interested in having a volunteer

Unsure if this can help but the owner of Rory's Guesthouse is Irish and from the U.S.
His name is Chad....  He might know more information on what your looking for.
