I’d pay $200 a month for a professional dishwasher, but really I’d probably have to pay much more.

> I would pay $5/night for someone to clean my families dishes after dinner.

Why not just use a dishwasher? If you wanted to break it down into a 'cost per night' then maybe rent the appliance or get it on interest free.

How big is your family?

Assuming your dishwasher(s) can hold 3-4 days' worth of dishes, you can totally do that now. Hiring a housekeeper to come in twice a week to do dishes and laundry is probably in your price range.
