Every detail listed here on services needed and hours/days are all flexible/negotiable. We have a four bedroom (2 are used as bedrooms, 2 offices), 2 bathroom (1 barely used) home. We have two cats, a dog, and two kids. This is too much for the wife to handle without some help, and I work all day (from home). We just need another pair of hands that can manage anything from vacuuming, picking up toys, to even playing with the kids while the wife can take care of something.
With regular scheduling the work will become more about maintaining, and will get easier. At first it would be a bit more work simply because we can't keep up with the kids in terms of cleaning vs spreading toys everywhere.
