Not sure I can help because I guided out here in Wyoming where there are no tree stands and hunting success is largly based on how willing you are to go up & over "that other" mountain by foot! Hard hunting for both hunter and guide. And the hunts were 5 - 7 days.
But our outfitter told clients that a tip of a $100.00 (or more if very pleased) was expected from them. Also, these hunts were pricey. Elk: $8,500.00; Mulies: $4,500; etc.
So go by the cost of hunt, difficulty for guide, and overall opinion of hunting experience and go from there. And if a $100 is lunch money to ya . . . go for it! The guide won't offer any change back.
As far as the cook . . . I never got a tip as a cook. I was paid by outfitter and that was that. He gave me some spiffs after the season, but all I got from the hunters was
mmmmmmmmmmmm . . . that was delicious!
