Then let me give you some (more and probably unwanted advice)
Staff. Get the staff in place asap. I worked in a new nursery from start up. She only looked for staff once the children started coming through the doors. This wasn't the best way, as more children came through, then she had trouble recruiting staff. She didn't have the money to pay staff without children.
Get yourself a good cook. Don't put the burden of meal prep onto your staff as well. It's a waste!
Consider being the Manager yourself, you save a Manager's wage until the business sets off. You don't count in ratios.
Don't give the jobs to young, just qualified staff. Make sure you have a reasonable selection of older and experienced. In my experience, parents feel more reassured with older staff. I'm not saying young ones are no good and everyone has to start somewhere but if you don't have early years experience, you need people who do.
Avoid wrap around care/school runs until you are established and have sufficient staff.
Get the basics in place and right then expand ideas. Start off with organic meals there, then expand to offer them as takeaways for busy parents then for sale on the shop.
Visit as many nurseries as you can. Don't walk in with an I can do better attitude. Walk in with the desire to learn.
Our LA has meetings whereby Managers from outstanding nurseries all meet once a month to share ideas. Get yourself into one as soon as you can.
Good luck. I really do hope it works out. There is no better job than a Nursery nurse and having done it for 20 years, there's no way I'd want to run a nursery, purely because I've seen the strain staff are under, nevermind the managers.
Despite people's misconceptions, it's not an easy playing with children day job. It's tiring, none stop, stressful and exhausting but those children are the ones who make it worth it.
