(someone) could sell sawdust to a lumber mill
Someone is an extremely smooth, charming, or persuasive salesperson, such that he or she could sell something to those who have no need or use for it. I can't believe you were able to sell an extra 200 units to the hospital. You could sell sawdust to a lumber mill!
