Mystic Nights has a pretty good free item search though I just found a dead link there:

I agree that it would be hard to sell stuff like that. I suspect not that many people are including the little details that can really make an image look more plausible. We're surrounded by stuff inside and even outside. There are plenty of houses and some patio furniture for example but something like a hose reel would probably be harder to find. Many such atems are available but you have to search the web and be willing to import/convert from other formats.
