Trademark - Painting trademarked design for profit
A person is running a business in Florida of selling custom made guitars & his primary products are solid colors or natural wood finishes. The person however does offer custom paint jobs per a customer's request. He does not directly advertise, but makes available images showing what can be painted, which does include a trademarked design. The guitar with the custom paint job with the trademark design is much cheaper than what major guitar manufacturers charge for a similar guitar with the trademarked design in association with the trademark owner. Only very rich guitar collectors would be able to afford the products offered by the major manufacturers.
As far as I'm aware the person in Florida is not paying licenseing fees to the entity, via his corporation, who owns the trademark.
How is it possible for the person to make a profit painting someone else's trademarked design & not be considered infringing upon the trademark?
