I may be the odd person out in responding to you but......
I think the previous things mentioned are great and are good things to offer and to look for, but I get frustrated by these "lists" of what makes a good daycare.
I tell everyone that anybody can accomplish those things. I can make sure my house if gorgeous, and spend money on having the best toys, and make sure my lawn is lush and green, but that does NOT mean in any way that I provide great childcare.
If I work 11-12 hour days with kids and spend the remainder of my "time-off" cleaning and doing lawn care I will not be well rested to take care of your kids.
Would you rather I be playing with and taking care of your kids or cleaning my house? Because most day I can't do both. I have actually had Childcare Social Workers say that something to be wary of is a perfectly clean house because that means something is being sacrificed in order for the provider to have the means to keep her house "perfect"
Now that I have gotten that off my chest. I do think it is important that you keep things nice looking and organized, but I think it is more important that you figure out what you want to offer. What is important to you? If you are someone that thinks that it is important to provide a "preshool" like environment then you aren't going to do well with a family that just wants their kids to play and be kids. And the opposite is true, if you are the type that doesn't think kids need to be formally schooled so early on in life, then you aren't going to do well providing that service.
Find out what you want to offer to families and expand on that. You will get parents that agree with your philosophy and the families that don't will find another daycare that fits them better, and everyone will be the better for it.
Once you get established, find out what each parent/family expects. I have some families that do want a daily "report" and I will email them or give them a verbal run-down of the day. Other parents don't really care what they ate on a day-to-day basis, or how many times they pooped, they just want to know anything non-typical (time-out, strange behavior, a new word, started to take steps, etc.)
You will never be able to please and offer everything everyone wants, so that is why I think it is best to find out what you want to offer and do that. You will be much happier and so will your daycare parents.
