Babysitter - Full-time / Part-time

I have 2 active boys ages 6 and 7 and a 1-year-old baby girl. All three kiddos love to play outside, swim, walk to parks in our neighborhood etc. The boys love soccer and baseball as well as riding their bikes/scooters etc. We are just looking for someone to help with the boys while Im with the baby or vice versa. As time goes on it would be great if someone could watch all 3 kiddos while I can get laundry, grocery shopping and errands done. I am currently a full time stay at home mom but looking for someone to help anywhere from a couple of times a week up to 5 days a week.
