How many designers per cabinetmaker?

Cabinet shops: how many designers do you employ vs. how many cabinetmakers on the shop floor?

I’m an owner and the only designer for 4 guys building. We hire out painting and install. I also make all the g-code for our CNC and do most of the client relations. I can’t keep up with how fast they build—granted, what we do is super custom and I can’t just make a Mozaik kitchen in an hour and call it a day.

Curious how this compares to everyone else doing similar work.

Edit: in our context “designer” = “engineer” = “draftsperson”; everything is custom from the ground up with no catalogue of products.
