Babysitter Needed for my Children - Full-time / Part-time

We will be in Romulus Friday through Sunday for a car event, and looking for help watching our 3-year-old son in our camper trailer while we are attending the event. It is fully stocked with kitchen, bathroom, and tons of toys. We will also be nearby. We have one well behaved dog that will be crated. The hours will be known when the event is closer and they post the schedule, but will be around 6 hours each day most likely, some hours between 8 a.m. to 5 p.m. Friday will likely only be a few hours if available, but Sat/Sun the bulk of it.
