If it doesn't have to be Santiago, PM me. My sister-in-law's mother collects clothing, etc. through her church in Santo Domingo, and they distribute it in Altagracia, just north of Santo Domingo. Kids there don't even have shoes I'm told. There is a church in Boston they are affiliated with who collect items in the US and ship it to her. I can get the info about the Boston church if anyone is interested in donating there.
