Part Time Nanny Needed For Two Sweet Self-sufficient Kiddos

I am seeking a part-time nanny. I travel for work and personal reasons from 2-7 days at a time. I would need full around the clock care, including taking them to school and activities, preparing meals, etc. during those times. Possible other smaller jobs as needed as well. Any housework would be limited to general cleanup of messes, dishes, etc. We play card games, board games, basketball, hike, eat out and enjoy watching movies together. S is a sixth grader. She plays clarinet in the band and is in art club. And she likes to play Roblox with her friends online. She just needs to be heard. W is a fourth grader and loves all things sports. He plays travel soccer and will start basketball in about a month. He needs help with homework. We have three cats, all of which are very sweet.
