Looking for a nanny. Live-in/Live-out Ideal

Hi,
I am looking for someone to care for my 7 month old daughter starting July. I also have a 6 year old daughter who will be at home in summer, and once school starts, she will be home for lunch and the rest of the day.

Need 8.00 am – 6.00 PM Mon-Fri. If the person is open to staying over a couple of nights when I travel ( infrequently) that will be ideal.

Need someone with good experience handling babies and managing two kids in general. Need someone with sense of responsibility, maturity and calm. Should be reliable and trustworthy with clean habits. Should have at least 1, and ideally 2 strong references.
