Babysitter Needed for my Children

We are looking for a great nanny for our 9-month-old twin girls in Westminster. We would prefer someone who could help out with light housekeeping (related to the babies). We would prefer a nanny who does not smoke, who is CPR certified and who has college degree. We are looking for 2 days per week to start, with the possibility of growing to 3+ days per week depending on my husband and my work schedules. I've listed Tuesday/Wednesday as the days we are looking to fill, but we are flexible on the specific days.
