Live In Elder Care Needed For 3-4 Weeks

My 73-year-old mother will be having hip replacement surgery. She needs help around the house with daily tasks and transporting her 2 grandsons (age 11) to and from school. She needs help starting immediately until at least 2-3 weeks after her surgery so approximately a month. There may be need for help once a week long term as well. She needs overnight care and all day for the next 3 weeks to a month. Pay would be $400/week. Private room and bathroom and food included.
