Welcome from me too!
I second all that has been said about the childcare side of it - we (
www.officreche.com, a space in Brighton, 1 hr from London on the South Coast of the UK) have been incredibly lucky to find a degree educated manager to run the childcare side of the business. I'm not sure what childcare practice is like in the US, but in the UK, flexibility is incredibly hard to come by - mostly because of the challenges that childcare professionals face in providing it. However, it is obvious that there is a market for flexibility, especially in times of economic hardship, only having to pay for the childcare that you need really helps modern families to budget.
My advice would be to look for a childcare professional who has initiative and vision and guts - and utilise their experience of traditional childcare and how your model will differ. They should be a shortcut to understanding your local legislation/licensing and the issues involved as well. I would recommend going to a university or college and finding a graduate, or someone who could consult on the theory as well as the practice - even if you don't hire them fulltime.
Both my manager and my deputy did their dissertations in flexibility in childcare (partly out of interest and partly because they were working at Officreche so in the middle of putting research into practice) and so have been absolutely invaluable in making Officreche a working reality and helping local families.
Apologies if I am telling you something you already know - just trying to contribute by sharing a few things that I'd have like to have known up front! We've been open more than a year now and the figures are beginning to stack up - but only because we are offering the option of flexible childcare on its own, not only combined with the office space.
Good luck to you all, thanks for posting on this google group
