Looking For Long-Term Nanny/Babysitter For 2 Girls - Starting April 1 (or Sooner)

We're looking for an experienced and energetic nanny/sitter to take care of our two daughters (ages 10 & 7) on a long term basis starting April 1st (or sooner). Hours will be approx. 35 hours/wk (plus extra hrs certain wks), since we both work full-time, with flexibility to start earlier on the handful of days when school is closed. Our older one is in 5th grade and our younger is in 1st grade, both at a public school (5-10 min walk away). Duties entail school pick-up and tending to all of the girls needs all the way through dinner & showers, plus mother's helper tasks/errands (meal prep), cooking for the girls, taking them to & from activities, and light housekeeping. Ideally, we wouldn't be your first family that you've nannied, but we're open someone with comparable experience.
