I knew a fellow who practically gave his business to his top guy (for a low price) and had a contract for supporting the owner's retirement. Perhaps a lease agreement with your top guy or someone who wins an interview. Perhaps fone a manager and you keep control until you trust him to make a sell-out deal.
Possible that there are PM guys who are sharp on wire EDM and milling who would be worthy of being the man on this. What is the ballpark number on this deal?
