Nanny Needed - Full-time / Part-time

We are looking for a great nanny for 2 children in Hopkinton. We would prefer someone who could help out with light housekeeping. We would prefer a nanny who has their own car, who does not smoke and who is comfortable with pets (we have one medium size dog). We are looking for daily help after school, including pick up. If possible, help on 2-3 mornings a week would also be helpful.
