I am planning to go to Thailand, Cambodia and Indonesia for a month starting in mid December 2016 and would be interested to have a company rather than traveling alone. By the way I am from Chicago, US.
My name is Kabilan, doing my Masters in Chicago. I have traveled extensively and had been in your situation many times. Its difficult to go back to your normal life after an adventure but that is the way of life. I used to work for 10-11 months, save money and take a break of 1-2 months to travel. As you said volunteering is quite expensive and had never tried. Right now I am traveling around west coast of US on a shoe-string budget till Jan 8th,2016 and you are more than welcome to join. My next trip will start in May-2016 around the East coast. My mail id is firstname.lastname@example.org and you are more than welcome to be in touch.
