Sitter Job in Saint Louis, Missouri

I'm a single, professional dad with two sons, ages 8 and 9, and am looking to simplify my life by having someone cook healthy dinners for myself and my boys. I lose that hour every night and this would allow me to have that time back with my kids. I'm specifically looking for an individual, a woman preferably, who would value a low cost or no cost place to live in exchange for a modest amount of cooking. If there's a night where you can't cook you can precook the meal. You would also do the grocery shopping (just for what they cook) and I pay for those groceries. If you were also willing to babysit a few hours a month, you could further reduce or eliminate rent, but that's optional. I live in a modest, but very nice home in Frontenac, minutes from L'Ecole Culinaire. The living area is in the finished, lower level which includes a fully furnished bedroom, full bath and windows next to a family area with a large flat screen TV.
