Hi! Not sure if you already know about this, but there is a website designed just for your situation! World Wide Opportunities on Organic Farms (WWOOF)ing is really popular. Essentially hosts who believe in sustainable farming practices offer room and board in exchange for labor. You might try out setting up a host account and I bet you'd get a bunch of requests!

There is even a website set up just for Chile!

Hope this helps
