Babysitter - Full-time / Part-time

I'm looking for a great babysitter for 2 children. Ages 9 and 10 yo. Ideally, I am looking for a stay at home mom or nanny that is open to watching my children during the day. Im open to taking the children to your home as long as it's safe. My child care needs are unpredictable but I can provide a schedule a few weeks in advance. Needed days are mainly for summer months until school comes back in. Then care would be needed, as needed.
