I want to go for a volunteer trip to south-east Asian countries or Africa. Although I found a website called STAtravel. I am looking for some more pointers for a lesser price. As far as skills are concerned, I am software and electrical engineer and a flute player with English knowledge and I can teach yoga too.
DIVOG (Disaster Volunteers of Ghana) seems to have some good volunteer programs in Ghana.
I have not personally travelled with DIVOG, but I found this site through a photographer that took his family on one of the family volunteer programs with them. A blog entry of photos from his trip is here: http://marksolonfstop.com/2013/01/05/dzolo-gbogame-ghana/
In the summer of 2010, my family spent a week living in the beautiful and lush tiny village of Dzolo Gbogame, a four-hour drive north of the capital of Accra. We lived in a small home in the village for a week and helped build a washroom facility behind a building which served as the village’s school, church and community center. Despite living conditions that would make most westerners cringe, the folks in Dzolo Gbogame were some of the happiest people we’ve ever met. I’m sure that being part of a tight knit community had a lot to do with that.

I don't think his site mentions DIVOG, but in a Facebook post the author of the blog said that DIVOG was the organization that they worked with for their trip, and that they took great care of them.
