Babysitter Needed for my Children

My wife recently died and I am trying to pick up the pieces. I need a caregiver to help my two kids (ages 9 and 12) get ready in the mornings for school since I work very early mornings and am not around when they wake up. Basically just to make sure they eat breakfast and get ready. Then drive them to school. Optionally, I would also be interested in having some light housekeeping accomplished after dropping the kids off at school. Start time would be 6:45 a.m. each school day. 2-4 hours per day depending on if simply dropping the kids off or also doing some light housekeeping.
