Help a volunteer to help

I would like to achieve my life long dream and calling and to travel to volunteer overseas in non-profit organization for three months. And with this three-month international period, I would be also able to complete the final part of my education. I've been waiting for this opportunity for over 15 years now. But, for my disappointment, it seems that I'm falling quite short of my funds. I have even sold almost every part of my belongings which had even a bit of value, but it was not enough.

So please be so kind and help me to help others.
