Childcare Needed

We are looking for a great babysitter for our 3-month-old daughter in West Seattle. We have an immediate need for next week as the person who we had arranged is not able to come, however we are looking for someone reliable who could help out on a weekly basis for the longer term. In the immediate future we would need help on June 16, 17, 19, 20, 21 and 23 for 3 hours at a time more or less. We would prefer someone who could help out with light housekeeping. We would prefer a babysitter who does not smoke, who is CPR certified and who ideally has a college degree.
