Babysitter for a 9 year old boy and 5 year old girl needed

We are looking for a babysitter for our two school age children- 9 year old boy and 5 year old girl. We also have a very friendly cavachon dog. This would be for a few hours after school on occasion and occasional evenings and weekend days. We will likely need some more regular after school help also going forward but do not have the details of what the hours might be yet. Returning to on site work etc. The job would likely involve picking the children up from school and walking or driving them home, preparing a snack, helping with home and playing.
