I have a strange question. Does anyone here do commission work?

There is a navy website that I belong to and someone just posted some information telling those that if they wanted a model of the ship they were on, to contact www.motionmodels.com. I went to that site and they don't list prices and want you to call them. That got me curious.

If any of you do commission work, what do you charge (not counting cost of kit and materials)?
