We don't understand how to acquire the rights to create an ebook from a newly published print book in Norway.

Question posted by Karin Holloway, on behalf of My Fat Fox Ltd in E7

The Norwegian publisher has asked us for our bid on it. We have no money to spend as we're just starting, so we have offered to create the ebook for free and to share the profits. They are going to a few European book fairs with it and will tell us if they have a better offer when they return to Norway. Where can we learn how to properly go about this?
