How can I create this 3D text video presentation? I don't have much clue about 3D modeling or Animation. I'm good at programming &amp; Graphic designing though. Thing is I want to do something like shown in this 15second video:


                
             

To be more specific, I need some 3D text as shown in the video as a slideshow. I need to create a 15-30 second video of that kind. Then I'll also have to record voice over it. That I can do in video editing.

If you know a quick tutorial of this kind, that would be a great help too. Kindly help.
I use the 3D Extruder plugin/script for After Effects CS5.5 to create the 3D text, then I'll create a camera to animate the movement. 

The tutorials plus network has a lot of great tutorials. Though I've never actually watched any of the ones on 3D text...
