Babysitter Needed - Now Hiring

I am looking for a reliable, flexible sitter for a currently 8-month-old infant. Ideally, I would like for him to go out on walks at least 2 times a day with his naps in between. He has a play pen and an activity table but still loves to roam around outside of those. If you want to play with him on the grass, I prefer to do it in the front yard because the backyard has too many sticks and patchy areas. His grandma can take over as it turns to the evenings on certain days. We have a dog- he is friendly and active. However, I don't expect you to walk him. Just let him out in the yard to play and pee.
