Recurring/Intermittent Babysitter For 6yo Boy

I am looking for a great babysitter for my 6yo son in San Jose. He's smart, funny, and relatively independent. I have one small dog. Car would be required due to transport needs. Important: This would likely be somewhat regularly but not set every week, unless there's one day that really works for you. I often need coverage after school due to my job and my mom cant always help. Usually somewhat short windows after school. Common examples would be pick up at school at 3, drop off at his dads at 4 (Mon or Fri) or pick up at school at 12 and drop at his dads at 4 (Weds). Occasional evening or weekend availability would be nice but not as high priority.
