Babysitter Needed for my Children

We are looking for a regular nanny for 2 children in Everett every Wednesday. One girl and one boy. We would prefer a nanny who does not smoke, who is comfortable with pets and who is CPR certified. One is in kindergarten from 8-3pm, needs child care from 3 p.m. to 6 p.m. The other is three, goes potty independently, and needs care from 8 a.m. to 6 p.m. I sometimes work from home, or, if not, at my office in nearby downtown Everett. I come home at lunch to walk dogs. I work for Snohomish County Human Services and my wife works in Seattle as a nurse.
