They list the various BBJs (which are based on 737s) at $5360-$5749 per hour.

BBJ3 is based on the 737-900ER
So call it around $50k all included.
Depreciation doesn't look like it's in that number either, but I'd say that's probably ignorable when you're as heavily utilized as a major carrier plane is.
That seems like a good ballpark number for something a carrier would agree to. Not something to do every day, but arguably worth the PR and not going to torpedo the company either.
The reason they're $0 on the report you're looking at is they're trying to sell you the report with the actual figures, not that those costs haven't been included.
Crew rates for majors are published. Here's Alaska's: http://www.airlinepilotcentral.com/airlines/legacy/alaska_ai...
Call the flight crew $300/hr, and the cabin crew probably another $150/hr.
