I am working on something similar to this. Make a list of chores available, assign an amount and decide how to display them. You can print them out and put them in an envelope, or create magnets or just make a list. Whatever is easiest for you and your family.
The point is to get the kids involved and helping out. I keep my amounts small because some things I shouldn’t have to pay for, so it is basically an allowance at the end of the week and it helps them learn how to set a goal, earn money to get it or decide to save it!
