Topic: Holow Earth 2 CGI shots needed

I need someone to do some 3D work for me. I need shots of these:

-Earth rotating. No background, so I can add my own
-A alien ship of your own design flying through space
-A 3D model of a basic building. A building with a falt roof, one window on the left, and a door in the middle.

I'd be very grateful for someone's help. You would be credited of course.
