How To Find A Buyer For High Quality Lumber Recovered From The Walls Of An Older Home?

The walls of my new house are covered with extremely high quality, knot-free, 8×1, tongue and groove redwood boards. I’m told that if carefully removed, they could be quite valuable. How do I find a buyer? Especially nice would be a buyer willing to help remove them from the walls for a reduced price. I’m in San Diego, California.
