Pet Care Needed

I have a large 110-pound German Shepherd named Titan and a devilish little black cat named Basil. I'm looking for a pet sitter to walk Titan once in the morning and once in the evening for around 30 minutes per walk. Additionally, I request that he be fed one scoop of food per visit. Lastly, the cat is a bit of a sour patch kid. He's sweet, but loves to play and wrestle.
