pages 09 to epub

I started a book of stories with photographs in page layout format in Pages not realizing until I tried to export as an epub, that it was not allowed. I understand that had I started the project just using document as a choice, I would have able to export the final copy to an epub form. Is there some way of moving all my material at this late stage to pages "document"? I tried moving it all to Word which does allow epub, but the formatting become unpredicable.

Thanks,

GH

At the end of the date, I would like our group to either access the stories via epub or read it more like a book on their non iOS devices.
