Household Manager Needed For Widowed Father Of 2

I'm a widowed father of two (daughter 14 and son almost 12) with a busy schedule, and I need help with getting the kids to their weekly activities, dinner prep, running errands, and some light housekeeping. I have a house cleaner that comes by weekly, but I need help with the kids' laundry, washing sheets/bedding, dishes, sweeping/mopping occasionally, and wiping off the counters and tables when they need it. Ideally, I'd like someone to be here from about 2:00-7:00pm, Monday thru Friday. During the summer months when the kids are out of school, I'll ask you to go full-time from 9:00am-5:00 p.m. (I'm flexible on these hours), and to keep the kids engaged when they're not in a camp/activity. Legal work authorization is required!
