Well I have done more research! I want to go back to spain and work, live cheaply for the Summer of 2004 (I know its way far off still, but i figured id better start early on this one!).
Here are some progrmas I have found.

-Aupair, through BEST program
http://www.bestprograms.org/
-Teaching english work study

-Interning in Spain

-Summer camp worker

Im still looking for more, so any more ideas would be great!!! Has anybody had any expereince with these programs or similar ones? I think all are legal, which is important to me. A couple are actually companies based in the usa, yet you would work in spain. Thanks for any input!!!!
