You sound like a very busy woman. The first thing that pops out to me is getting your children involved. I know...easier said than done as I am fighting with my kids right now to get their rooms cleaned. It seems like your children are at least old enough to make their own lunches and two of them old enough to do their own laundry. Both are very easy natural consequence changes....make your lunch or clean your clothes...or go hungry and wear dirty clothes. Let them make the choice to what they want. Otherwise it seems like you are doing the right things but are just busy being a parent.
