We are moving to Chile on Sept. 6, and it looks like I might be working part time (and part volunteer) at a bike tour company called La Bicicleta Verde (http://www.labicicletaverde.com/index.php).
It's founded and run by an American, and almost all of their customers are English-speaking, so my low level of Spanish won't be a barrier. I might get to do some tours and even some bike mechanic work. I had a skype chat with the owner and he told me that they are very likely to have at least some paid work for me, and I said I'd be happy to start as a volunteer in the meantime.
In a new city, working on bikes and meeting bike-friendly people sounds like a good way to start out!
