Experienced babysitter needed for two children ages 1 and 9

We’re looking for a babysitter to help with two children. We are looking for someone 2 days per week, typically m,w, or f from 6:30 AM to 12:30 PM. I'm an rn so my schedule varies. The ideal candidate is comfortable around an Australian shepherd and cats, but does not need to care for the pets other than letting the dog outside in fenced in yard. A car is necessary for transportation to our home but won't be necessary to travel with the children. The 9 year old will need to be gotten ready for school and on the bus at 8:30 so after that it will just be the toddler. This role involves engaging with the children, ensuring their safety, and facilitating activities.Children's father will be home but will be sleeping as he works night.
