Nanny Needed For My Children In Los Angeles.

I am looking for someone who can help my wife take care of our two kids while I am out of town. They are ages 6 and 3. This person would need to pick up our kids at school, which is located within 5 mins of our house. Pickup time would be 5 p.m. Then, help watch the kids until 8pm, when my wife puts them to bed. My wife would be home most of the time, but may run errands in the early evening so there may be points when the person is solo with the kids. Specific tasks may include occasional help preparing a meal, playing games with the kids, getting them dressed for bed.
