I shot a short down there about 10 years ago and I will tell you what I know. It is a small community of filmmakers there. The production is almost exclusively for TV commercials. TV series are traditionally imported from neighboring countries.
It is a wonderful country that has a frustrated feature film community that is almost non existent. I almost went back last year to shoot a low budget feature but my schedule wouldn't allow it. But just by talking to the producers it was clear that nothing had changed in the last 10 years. For what ever reason, movies simply are not made there.
The 1st AC I worked with and whom I have not had direct contact with for several years is Richard Vera Caceres. Through his Facebook posts it appears he is working full time, on commercials of course. You could try reaching out to him and perhaps get some insight.
