Have made several things over the years for charity auctions or sales.    Have had a couple of people then ask if I would make them a similar object but at a price less than sold at the auction.    Said no. to low.  
Find it is a small market for a lot of things as most do not realize the cost of the wood, hardware, etc. let alone the time to make it.   Example:  Pennsylvania Spice Chest.    Person seriously ask if I would make them one, would pay $500.   The Walnut and hardware, cost close to or more.     

Do see items on Etsy and similar sites.   Interesting subject.
