Babysitter needed for 5 children, ages Toddler to middle school

Hi sitters! We need a dependable babysitter for our five grandchildren, ranging from infant to middle school age. The start date is flexible, but we prefer someone available from July 10th, working Saturdays and Sundays from 12:00 PM to 8:00 PM. The sitter must have a car and be comfortable around our medium-sized dogs, though no pet care is needed. Experience with multiple children is essential. Language skills is a plus
