After I read the following post at the blender.org site,
it might be an idea to inform you about companies that sale 3d modelling/animation software, that is in fact free.

this post covers the topic more in detail:
http://www.blender.org/blenderorg/blender-foundation/press/re-branding-blender/

and this are the sites that are trying to let people pay for FREE software:
http://www.illusionmage.com/
http://www.3dmagix.com/

I think most people won't trust these sites anyway, but it would be sad if they could make ANY money!
