I think torontokids has a great idea. I was going to say the same thing!
Most parents with babies and toddlers probably will have issues choosing you. Some because ur male but others because of no experience. But.....if u offer a school age program u will probably have better luck! U have your days off ...u would offer before and after school care. You would then have them on pd days, Christmas and march break and during the summer. U can do and probably offer a lot more to that age group. Soccer, hockey, swimming, science experiments, etc and etc. Also parents will feel more comfortable as their kids are older and can talk if something went wrong. Also you will be giving your school age daughter some playmates!
