Current College Students - Babysitter for 26-27 School Year

I am looking for someone to care for my seven year old nephew who lives with me full time in Dedham, MA. The ideal candidate would have availability 4x/week for 20-25 hours, with hours being Mondays 12:00-5:00, and 3 other days, 2:30-6:30. I am needing someone to pick him up at his school in Lexington and bring him home, some days, to his therapies, such as Speech and Language. He is dynamic, fun, imaginative, curious, and loving. He responds to someone that is playful and kind that can meet him where he is at and engage on his level. Priority given to candidates that have experience working with children who have specialized training, or has special interest in psychology, speech and language, and occupational therapy. I am hopeful for someone that has capacity to commit to the full school year, with some weeks requiring more hours given school vacations. There is opportunity for some additional house management such as scheduling appointments for him, meal preparation, light housework, and other administrative tasks. $25-30/hr depending on experience
