humanitarian and development aid

i've done a pretty good amount of research on my new career path.  read a lot.  found a lot of useful information.  just like any other career, it is going to be hard to get my foot in the door.  everybody in the field has stressed the importance of getting field experience via volunteering or interning.  only problem is these field experiences need to be done in developing countries.  i can't exactly just pick a country and take off.

i have looked into different programs by different organization that claim to give you just that but each program is a couple thousand dollars.  then i came across an article that says that not all programs do as much or help the host country as much as you'd think.  makes this whole process a lot harder.  how am i supposed to know which programs aren't actually a waste of my time and money and ends up hurting the local economy?  if finding a good program isn't enough, most humanitarian organizations require around 5 years of experience.  its an experience that is not easy to just do...however, some people have gotten a job in the field after doing 2 years in the peace corps.  unfortunately for me, i am not ready to leave for two years nor am i ready to take on the whole peace corps selection process which i've heard takes awhile.  i am up for taking off for a year.  it's one of those investments in your future you have to take.  instead of spending $30,000-60,000 on a graduate degree that may take up to 2 years, i will need to spend 3-5 years in a developing country.  the only program that sounds serious right now will cost about $10,000 for one year (incl. personal expenses, $350/month.  though i could probably survive on less.), not including round trip airfare.  if i do 2 years, that's $20,000.  this is going to be like doing a 2-part grad program.  first part is gaining field experience, and the second part is grad school.  total costs would be $50,000 - $80,000.  woe is me.

however,  there is one way i can gain the field experience without that hefty price tag.  instead of going to africa for two years, i can go to thailand.  i have relatives there.  a few of them having been doing humanitarian work in the villages off and on for many years now.  mostly with material donations.  i can still do this somewhat on my own.  though i've always felt unsafe to walk around by myself over there.  this will be interesting.  i have a lot more thinking to do...
