Problem with parents sending lunches is the kids are too young to understand that one kid get a granola bar for snack and another gets orange wedges and another gets pudding. They are also too young to unwrap, open containers etc so you still end up doing part of the prepping anyways. Also unless it is sandwiches every day the parents may be expecting you to warm the food so by the time you zap five lunches in the microwave it is easier to make a meal and serve it to everyone. And it means deductions from taxes. As someone said parents would expect to pay less so for all the hassles you are going through in helping out with the meal you are getting no money for it. Also since it isn't common for parents to have to send the meals you would likely lose out in getting kids as parents would consider it too much hassle to deal with everyday and go to someone that provides meals.
