This is really interesting information, ( I was not expecting such a good response), especially if it is possible to get EU/City funding from 65% and/or above.
Realistically, with this sort of project, you want to approach it from the point of view of not getting any funding (except the specific kindergarten funding that's available to all - as Olaf outlined) at all. EU funds are in very short supply in any sort of prosperous Polish area (especially cities, with the possible exception of Rzeszow, Lublin(?) and Bialystok) - and Poland isn't too good at administering the EU funds either.
City/Provincial/National funds are a possibility, but again - there's intense competition for this kind of thing in cities, especially given the vast amounts of unemployed graduates being churned out. However, if you can bring something "new" to an area that doesn't have it, there's a chance - think (for example) Montessori in a small rural city.
We are hoping to start with a small kindergarten to care for up to 25 children.
Yes, sensible idea. I'd investigate renting rooms from already existing educational establishments - it would be the easiest "path".
We will also try to contact your recommended person Michal, for a discussion on the matter.
Before you pay anything to him, give me a shout as to what he's charging. Lawyers in Poland have a nasty habit of charging a small fortune for foreign clients ;)
and find the relevant City department to get an understanding of the exact requirements to start the kindergarten.
Any idea where you plan to move to?
If you have the funds to do so, then a private nursery run according to UK standards rather than Polish standards could do very very well - people here very much perceive "foreign is best".
