Ok, if you're really looking for speed, what I think you need to do as the owner / manager is setup a streamlined, reliable, high-speed set of processes, prove out and debug them, and then train your hires to use them efficiently. Come up with standard processes for all of your different common types of parts, with template files and any pertinent notes, so they can say, "This looks like a type 7A part", load the template, drop in the client's model, apply the toolpaths to the geometry, and then quick deal with any special circumstances. Post, verify, setup sheet, done.
