Temp Nanny/chef Needed For 6 Weeks Could Be Longer.

We are a family of 6. We have 4 kids aged 16, 14, 14 and 10. Our current nanny needs surgery and will be out for 6-10 weeks. We are looking for someone who can pick up our 10-year-old from school, take her to after school activities like dance and gymnastics, cook healthy meals for all 4 kids each evening, prep our 10-year-olds school lunch for the next day and light housekeeping to keep the house tidy. We would prefer a babysitter who does not smoke and who is comfortable with pets. One who can help our daughter keep on track with homework would be great.
