Nanny Needed

We're hoping to find someone to spend a few hours with our almost 7 yr old in the week before school starts. Morning would be best, but we're flexible since I work from home. It would be nice to have someone that is comfortable in the water (a swimmer or a lifeguard even) as we have a neighborhood pond and our child loves to swim down there, but it's not necessary. Our child also likes riding his bike and playing outside.
