Afternoon / Evening Family Helper Needed For 2 Children

We are looking for a family helper who can help us with dishes, kids laundry, cooking for kids, bathing kids and tidying up around the house. There may be a few occasions where driving is needed to pick up the girls. We need someone who is available at least 20-30 hours per week. Typical hours would be 2-8 p.m. on the weekdays but at least one day (usually Friday) where we'll stay out until 10-11 p.m. for date night. We are a fun and laid back family who is looking for someone "long-term" (at least 1 yr commitment or more).
