I would like to use a world map in my film. Can anyone advise on purchasing rights to the map. My film group is not for profit but we plan to pitch it anywhere and to anyone so we need to cover ourselves regarding copyright.

Please advice on resources out there, particularly with non-profit organisations in mind. We may just pay ourselves for the expenses we incurred but as a company we are not for profit.

I've looked at google earth movie maker but at 400$ + 200$ for the option it is too expensive.

Any other ideas?

I already did a search of videoforums for 'map' but no similar query has been posted.
