Babysitter Needed for my Children

We need a babysitter for our 2 children in Mercer Island. Must have experience with toddler and preschooler. We're out of town and visiting for a wedding and need someone who can watch the kids in the afternoon, have them eat dinner and a bedtime snack, and do the night time routine. Will need to get references. Would like to meet and do a trial run on Thursday, Oct 1 (flexible, but can do afternoon) Actual wedding will be on Saturday, Oct 3. Afternoon into the evening.
