What would be a reasonable asking price?

I have been asked to mind a nearly 2 year old for one day a week.
They would drop him off here and I'd mind him with my 3.5 yr old and 1 yr old.
They'd provide nappies I'd provide breakfast, lunch and snacks.
It would be from 7:30 til 5ish.
I've told them I'll consider it, will be nice the extra $$, cash in hand, so what could I ask for?

TIA.

Given that you've got your own kids there, the going rate for a "mummy nanny" is about $8-10 an hour.

Thanks for the reply, thats good cause we were actually thinking the 80-100 mark so would be same as its nearly 10hrs work.
