Nanny For Toddler Needed (recurring 2 Week Periods)

We are looking for a part-time nanny to primarily look after our 2 year 2-month-old toddler. I will be routinely traveling for work, in town two weeks at a time, every 8 weeks. I'm planning on bringing the family with me. My wife will have her hands full as we also have a 5-month-old, so we'd like to hire some extra help during this time. We would prefer someone who has experience with young children, and could help out with light housekeeping. We would prefer a nanny who has their own car and who is CPR certified, and non-smoking.
