Or you could go down to your local lumber yard, find the species and grade you plan to sell, figure in what it would cost you to cut the stuff per thousand, and put an ad in the paper or spread the word by mouth. If it doesn't sell, your price is too high. And sell the waney, warped stuff cheap or throw some in for free when a guy buys some nice stuff. People remember that. They'll come back. Same with logs. If you provide straight, solid stuff on a regular basis, they'll usually scale you high, and might take an occasional load of junky stuff as a favor. If you try to sneak junk in, they'll catch it and won't like it. May not buy from you again.
