Looking For More Than A Nanny!

Hello. I am a single parent with a demanding profession. I'm looking for someone to help with my 6-year-old throughout the week. He's sweet but a handful! He will need someone who is comfortable establishing boundaries. For example, I work from home so at times it can be difficult for him want to involve me in play. In a perfect scenario, this person would come over at 3 to help me with some straightening up and/ or errands before getting the little guy off the bus. Once we are comfortable with one another I would also need this person to do an occasional overnight, mostly during the week.
