I will be babysitting starting at 4:30am. 3yr. 7yr. 12yr. & 9yr. 10 hours a day 5 days a week. How much should I charge?

I'm a qualified childcare worker and work for $24 an hour on casual rate. When I do babysitting throughout the day I generally go on about $10 an hour, more for weekends, nights or longer hours ~ like you!
Seeing as 430 will be hard :) well would be for me! I would suggest approx $80-100 day and therefore appro $500 a week.
Goodluck with the early mornings*

Where do you live? I think you have to go by regional prices. I live in mid-michigan, and the going rate for daycare for one child is $30 a day, say 8-10 hours, and all I bring is the diapers. (My son is two). The daycare lady provides the breakfast, lunch and afternoon snack with subsidies from the state food program. This is a home daycare not a facility by the way, those run $45 a day. If you are not licensed by the state you live in, I would get licensed, it can be illegal to accept non-related children for pay. Check around with some other providers. Just call some up out of the book and ask them their daily rate. Hope this helps.

Yes it just all depends we have programs here in Atlanta that cost 100 dollars a week per child, others cost more.

Are you going to watch them in your home or their home ?
Are you insured for daycare in your home if one of the children get injured.

Also when is since three of the children should be in school during the week
