Babysitter - Full-time / Part-time

I'm looking for a great nanny for 3 children. We have a total of 6, but the older children will be in school. I am looking for someone to stay with our 2-year-old during the day and to drop off/ pick up our two older girls (ages 3 and 4) at their pre-K counts program. This would only occur a maximum of two days per week. The hours would be between 6:30 and 5 (when I get home from work). We would prefer someone who could help out with light housekeeping. We do have pets (2 golden retrievers), so please consider that when applying.
