Can't Decide Which daycare.....suggestions?

I am having the hardest time deciding what to do....usually I can make a decision and it works but this is different.....looking for suggestions.

Due to the economy, I need to work. If it was up to us, I would be staying home full time and had that was the plan. I wanted to open my own preschool but we are adopting through DHS and the kids are considered foster kids for the first year. And you can't do daycare with foster kids living in your home.

But plans change. So, I am a substitute teacher so my schedule is easy and I really have no work issues to bring home. So I am home early and no stress from my job.

Last year our son (will be 5 this fall) was in a in-home daycare and she did a purchased preschool program with the kids. There wasn’t a lot of creativity with the program but it taught some good values and behaviors. Last year there were 4 fulltime and a few kids here and there. This year there will be 5 preschoolers full time (including him), a new infant and a few other kids here and there. The preschool room is very small but we were happy last year so this isn't an issue with the provider or his care. This is not in our school district. We plan to send him to public kindergarten and then hopefully private school after that. So I have been looking for new daycare. Here are some options ~

1. keep him there – very structured, very routine

2. new place in our school district – she has been doing this for 12 years, current and former parents of the kids love her. Huge play area – indoors and out, animals, lots of play time, not supper structured (which I am not and know he will get tons of that in school). Does more hands on activities. Less expensive that #1

3. Christian preschool and elementary – not in school district so he could go there for K or we’d have to find a new place next year. Which isn’t that big of deal to me. Less expensive than #1.

So if we did #1 or #3, he would or might have to switch next year. The other issues we have is that we are adopting and do not know what / when everything will be happening. So there are more changes coming.
I'm trying to focus on what is best for him for this year and not think of all these other things, but I have to take all this into consideration. Our son is not shy at all and easily adapts to new things.

My first instinct is the Christian school. We’d like to home school the first couple years but the likelihood of that happening isn’t high b/c of job issues with husband.

I know this is such a family by family issue but looking for some suggestions from people who aren’t as close to this and maybe has a different perspective that we do. Or might think of different issues than what we have thought of.

Thanks so much!
