Fisher 440 Restoration/ rebuild

Could someone provide me with a broad ballpark estimate of the labour time in hours to restore a Fisher 440? I am referring to electronic components. Not rushed, not slow. Just careful, steady, professional work. Otherwise a price that I'd have to pay for labour to do this.
Thanks
 
I rebuilt a Fisher KX-200 a few years back. The rebuild involved replacing all the capacitors, changing resistors to a different value so the tubes lasted longer (lower amperage through the tubes), rebuilding the switch/volume control. I would say it took about 20 hours working slowly and methodically.
