I need help regarding what to charge for a B-day Party for 7yr olds.
How do you know what to charge? They only want balloon twisting and face painting but I've have never done a b-day party before. I normally do hospitals and nursing homes but need to supplement my ministry some how so decided b-day parties would be a good way but have no idea what to charge. HELP PLEASE! any suggest would be taken into consideration.
