part-time nanny for two great kids needed

We are looking for a part-time nanny to work M-F afternoon, 2-6pm, to pick up our two elementary school kids from school, take them to after school activities and sports, prepare dinner and snacks, and tidy the house. We also would like someone to clean the house and do occasional errands for an additonal 10 hours per week. This may be you if you would like the additional hours, or a different person, if you don't. Must speak excellent English and be very competent and experienced driver with own auto insurance (though you would drive our car). Prefer a long-term commitment potential.
