Babysitter Needed For Evening Help

I have five children (including a 2-year-old) that requires supervision in the afternoon and evening. Four of those five are homeschooled in the morning while the toddler plays nearby. There are also two older children (16 and 13 with special needs). However, they are independent and will not require direct supervision. A structure is already in place, including chores and meal plan. Sitter would need to supervise younger children while I sleep in the afternoon and assist my fiancé with dinner and night routine.
