Childcare Needed

We are looking for a great babysitter for our 7-year-old son in El Dorado Hills. We would prefer a babysitter who does not smoke and is CPR certified. We need a baby sitter for date nights, weekday evenings, school breaks, or daytime weekends. No guaranteed hours, as needed basis. Great for a college student looking for variable, as needed work on evenings, nights, and weekends. Opportunity for overnights if a trusting relationship is developed. Must be comfortable with large (but very friendly) golden retriever.
