J.,
I had my own daycare about 17 years ago before I had kids of my own. I was licensed and would suggest from my experience going that route. I know it's more work with taxes, etc. but I was able to get some assistance with meal reimbursements etc. I had business cards made up and put flyers up around my town - at the library, local businesses, churches, schools. I had clients pretty quickly and I think most parents feel better if they know that you are licensed. You have to have CPR/first aid training, etc. so they probably feel safer.
Having you own daycare has pros and cons to think of before you take the leap...pros: extra income, being able to work from home, having friends for your kids to play with, getting to play with kids and feel like a kid yourself...cons: your kids will have to share you, your house will be more trashed, no matter how much you pick up, you are tied to the house alot more, you will have a lot less "me" time, even though you're home, you will have to put the job 1st, and not catch up on laundry, cooking, errands, phone calls, etc.
I liked having my day care for the most part and really got attached to the kids, but it got to be too much for my husband and I because he worked afternoons and I worked days from our house and we never got to just be alone except on the weekends. I hope I gave you some insights and didn't discourage you if this is something you really want to do. Just think through the good and not so good aspects of it and that will help you make your choice. Good luck! :)
