Advice Needed: How Much to Charge for Outside Outsider Art?

A few years ago, Mr FS, who heretofore had evinced no interest in his artistic side, began to make creatures of wood. I suppose he can be classed as an outsider artist since he has never had a lesson. Still, he has been to the Louvre and other major museums, so I suppose he's a semi-outsider. The art is definitely outside.

The creatures reside on our fence and the outside walls of our house. They have been attracting a lot of attention from dog walkers and walkers. Many ask if they are for sale. So far, we've said NO. But the creatures are multiplying a bit too fast and this morning a prominent local resident, who has been involved in the local arts community, said she'd like to buy one, and to help us sell them. She knows well-connected types, and hinted at a freebie or cut price for herself.

The prominent resident told Mr FS he would have to determine a price. (Earlier she had herself suggested something like $1,000. This seemed crazy to us!) Of course, teacher types like ourselves tend to undervalue our time and our labor. So, Readers, another question: how much could Mr FS charge for these large creatures, some of which take him more than 30-40

hours to complete?
