Well it is a very interesting proposition.

As a company I would be attractive to me to supply completly finished metalwork and guarenteed faultless feeding, proofed and ready to go. Shot and regulated. Or in the white if somebody wants to arrange their own engraving.
The woodwork takes time and is a large part of the cost. That way a customer could decide on their spending level by supplying and finishing the wood themselves.

Food for thought.
