There were a couple of things like that in Sydney near where I lived that were like $10-12 per hour. Qualified carers etc.
I'd really only consider paying more than that for specific lessons or something. Sports, dancing, drama, music, art(not just paints and go for it, but something really involving)
Who are the two other carers? What qualifications do you and they have? What's the venue? How many hours/days would you opporate? Is it near to cbd/major shopping area?
As an idea maybe have like 3 hour blocks, 3 x 30 minute lessons, and employ a toddler/preschool dancer teacher, someone who'll do something else and someone who'll do maybe an art activity, have a group sports session and throw in a story time to start and cut fruit to finish, you be the "coordinator/floater" I'd say have 12 kids, (so 4 per activity) I'd pay $40 for that if jasper wasn't in daycare.
