Looking For A House Manager In Museum District For Family Of 4

We are a family of 4, kids are 10 and 11. We live in a house and go to Presbyterian School very close by. We are looking for someone to help with the afternoons/evenings doing some tidying up & cleaning from the day/afterschool, unpacking lunch boxes, organizing what needs to be done, laundry (folding and putting away) when needed, meal prep for dinner and school lunches following day. If there is an errand that needs to be run that would be very helpful along with potentially a kids activity but this will be kept at a minimum since I will be able to do it if I have help. Additional babysitting in evenings may be a potential. My husband travels a lot and I work from home so an extra pair of hands is needed! I am looking at Mondays & Wednesdays while Tuesdays and Thursdays are more flexible in afternoons/evenings.
