Sitter Job in Ann Arbor, Michigan

I'm looking for someone to come to my home, in Ann Arbor area and care for my three children, ages 5 years, 3 years and 10 months. My son will be starting school in September, so during the school year would just be the two younger children for the majority of the day. Must be dog friendly as well. I work 4 days per week Tuesday-Friday, some weeks I may also work Monday (will be compensated for extra day). My husband needs to leave for work around 7:15am and would be home between 5:30-6:00pm. I'm looking for someone to start almost immediately. References will be checked and you must be drug free (obviously) but I feel the need to add that.
