Yeah, the market for photography or anything really, would be a smaller in Chile, and the shipping costs would be a big barrier.

Unfortunately, I don't know of any places that would reliably buy or book product shots. There are stock photography sites but those pay next to nothing. (I sold one picture on istock, 0.25¢ not even over the threshold to get paid!) 500px has a good pay structure, but I haven't sold any there. Steemit has actually paid the best as for online photography. I've done some interior stuff and portraits, the online part of that would be my portfolio, which makes it very easy to site people my work.
