!PC'd for 9 years....cost plus food.....does not matter what they eat ie could be lobster or red beans, they are paying for my expertise.
Have a list made up of veg, meats, how hot if too hot, herbs/spices, fruits.....
go through them all with potential clients. It's amazing how the "I'll eat anything" client really doesn't like onions or tomatoes....but "eats everything".
Take care of yourself. If you commit to cooking for someone each week then if they go on vacation you still need to be paid. Coming up with fillins is impossible AND you have allocated that time for them. Make sure you put this in the initial agreement.
I'm fast. I can shop, fill a fridge in a very short time and serve lunch usually within 2-3 hours. So I don't work by the hour for my one pc client (a priest that pays my health insurence). But when I pc occasionally....comes up with usually old clients wanting me for a week or in one case 3 mos after surgery....I charge X amount for time....drive time, shop time, cooking time, cleanup, etc....so it's hourly + food.
Work out specifics prior to starting, have a set business operating plan so that there are NO problems with lack of communication further down the pike.
I raised three sons for several years PCing....good money, great way to be creative if you pick the right clients. Good Luck!
cooking with all your senses.....
