Render texture maps

I am doing some architecture renderings, and need some new flooring maps. My work has the arroway textures, so it is a good start but a client wants something a bit more specific that arroway does not have. Are there other companies like arroway that makes tilable flooring maps? In specific, I am looking for a large, wide (broad) plank bleached floor. I have tried photoshopping one of the maps I already have, but it gets pretty washed out and loses too much detail.
