I've almost always had a CAD guy to do mechanical drawings, design really, and to lay out PCBs for me. I even draw schematics on paper and let him create the library parts and enter the schematic. We discuss placement, routing, thermal issues, whatever, and he lays out the board and does the whole package: schematic, pcb, fab drawing, assembly drawings, BOM, gerbers, PDF files, front-panel fab and artwork. A decent density multilayer board may take him 3 or 4 weeks for the whole package, and that saves me a lot of time.
I do review the layout in process and check/tweak the final layout before we gerber/release it.
