Volunteering around the San Juan Area

I want to spend 6 months to a year volunteering around the San Juan area.  I would like to use the opportunity to meet locals my age in their 20s.  I speak limited Spanish.

Any suggestions?

Not really but, Google is your friend: http://www.google.com/search?hl=en&q=vo … uerto+rico

The better your Spanish, the easier it will be so I'd work on it.
