It's basically unprofessional to discuss salary, especially if you're the employer. It exposes people's private arrangements, and can lead to all kinds of budget negotiation hassles, not to mention hurt feelings.
I have the complete budget for Star Trek VI, and it's not very useful except to know how much each department spent, and those are all union rates, mostly in L.A.
I live and work in the San Francisco area, and it's one of the most expensive areas in the country, so I might have to spend $1,200 to rent a fully equipped insert stage for a day, whereas someone in another part of the country might get it for a third of that.
My experience is that is you are doing craft services for a full shoot day it's going to cost you something like $20 per person (meals, snacks, water, drinks, etc.). If someone on your crew is willing to cook meals to bring in, that can lower the cost, obviously. If you're paying for catering, the costs go up.
When I did
Stagecoach in the Sky for the 48 Hour Film Project I was not allowed (by contest rules) to pay anyone, so basically the budget was all for rentals, equipment, props, expendables (gaffer tape, etc.), craft services and meals. I don't have the receipts in front of me, but I remember we spent ballpark about $300 to use the plane as the set, about $400 in grip rentals and purchases, $200 for food, maybe $100 for costuming, another $100 in hair and makeup supplies, etc. The day easily cost over $1K, and even then a lot of stuff (audio gear, camera, etc.) was provided for free by some of the crew who had the gear. This was for a one day shoot.
