I have actually seen them in Ripley/Saga, but you know that it changes with the current "style", so they might not be in this season.
Have you tried Plaza Hogar? They are mostly the Villa el Salvador workers, and if they don't have them, they can make it for you.
I added some fixed furnishings to my house, and the interior designers work with several Wood craftsmen, but of course you pay the additional designer charge (which is not necessarily a bad thing). Email me if you are interested in the designers' info.
