By 'corp guys', do you mean owners? If so, some are cheap, but many aren't. The 'K-Mart' types come around when they see the PFT guy take a walk a day or two before a trip. Then they either bite the bullet and hire a full-timer, or hand the airplane to a management company. I've seen a couple mgmt. cos. eat the owner up in 'expenses', too.
Bottom line, there's no free lunch.
