Pricing for babysitting?

I’m thinking about starting to watch children. So far I have one 7 month old and a 2 year old. I’m about to have another 7 month old and I’m wondering about pricing? I am licensed and childcare and I know lots of things to do. Scheduling, lesson plans and what not. I probably sound a little dumb I’m not good at wording things lol. I live in norther Arkansas and I’m not sure what a good price is for 5 days a week and 8 hours a day or less never over.
