Childcare Needed

I am looking for a babysitter for 2 children in Eugene. It would be regularly scheduled Tues/Wed/Thurs, every other week, for school pickup, transportation to activities, and time at home. Total of 20 hours per month, with the possibility of more for one off events. Must have their own reliable car and who does not smoke. Preference for someone who is CPR certified and who has college degree.
