I don't know about your state, but ours has a list of loggers. Contact your local state forester, and they may be able to supply you with a list of loggers.
Are you looking for a specific type of log, or just logs? Sometimes other mills will supply you with logs if it is something out of the norm.
We sell short logs to a WM type of mill. Short logs are not profitable for us to cut. He also takes the unusual. English walnut, catalpa, and things with lots of metal. We also get rid of small logs to scragg operations.
We find that logs that are too small or too large for the operations are more profitable to sell than saw. If you have a niche market, maybe you can use them.
If you are looking at the high end of things, maybe veneer rejects would meet your needs. A thin kerf band can be used profitably, if you can capture the increased yield in a reasonable amount of sawing time.
