Althought I could never do that lol if you feel that's something you would like to take on, then by all means. I agree with dreamalittledream. You should break down your day to hourly and charge hourly. Most likely, they'll take whatever you charge because finding care for those hours will be relatively impossible - unless the get a live in nanny, which cost much more than that. The fact that you have guaranteed hours for a year is great! I would definitely charge per hour. I have a friend who is opening a daycare and she charges $35 a day. She worked 12 hours one day and 6 hours the next. So, in two days, she worked 18 hours and got paid $60. That's not fair at all. Anything over 9 hours, I charge the additional time per hour.
