Isn't that what you want in a wholesaler, technically well executed?
Wholesalers have nothing to do with design, colors, even materials, their job is to execute the project according to the design provided.
This highlights what can be wrong with the sign industry. Non designers design a sign they cannot design or make, then farm it out to be made by people who can technically make it, even though the final product is a visual failure. Signs are more than ink on vinyl. A good sign has an esthetic value that is more than the sum of it's parts. An artistic element that creates the sign's true value.
