ActionScript 3.0 :: 3D Project In Flash CS4?

I will be doing a band's website to promote their music, and the idea is to make a 3D render of a circa 1960's Ed Sullivan Theater stage, where the Beatles had their legendary Television performance.

The difference is that it would be slightly modernized for the 2000's... so there would be a large screen at the back ala U2.This is the Ed Sullivan Theater Stage when the Beatles performed on it:

Instead of the beatles, there would be 2D cartoonish cardboard cutouts of the band I am doing the website for. (The idea is that the cutouts are stand ins for the actual band)In flash, clicking on a navigation link would perform a camera weave through the cardboard cutouts to a jumbo-tron type of television screen at the back of the stage, where relevant information would be displayed.

The render doesn't have to be photo realistic. the band has a running cartoonish theme going on 3 of their album covers. I would say something akin to how the Gorrilas videos look would be appropriate. I have a friend that is a cartoonist that will be a consultant on this, and do the drawings of the band members.

Again, it's just the stage that needs to truly be in 3D, as the band members will be 2 dimensional. The band members will be carboard cut-outs on the stage. They're placement on the Sullivan Theater stage will be in 3D, though.I don't have much money set aside for the development, so I need a cheaper solution than using Maya or whatever the big boys use to render 3D models.
