Any moms out there that stay home and run a daycare

I need some advice, stories, or opinions. I have 3 kids. 4.5 yr old. 2 yr old. And 2 month old. Im looking for a new job and can't find anything for stay at home. What are opinions or if you do it on staying home and finding a few children to babysit? Is it worth it? Do you go to crazy with the kids? I probably wouldn't take in more than 2 or 3 other kids. How much do you charge?
