If your showing up and doing a one time dinner, 35.00 an hour and they buy all the food or give you money to go buy it once they approve the list.If it is on a daily basis for dinner only maybe 40.00 a night. It really depends on what your going to be doing. If you making fancy involved meals you will make more than someone cooking a basic meal. Call some personal chefs in your area and act as a customer and get rates quoted to you, to stay within the going local rate.
      Answer1:Here in Seattle, almost every personal chef charges $300 plus the cost of groceries for one session (where they make 10-20 meals).
