I need to make 3D video animation from a 2D Logo of a business

Information for the business: We sell heating and cooling systems
Design details: I would like to have a video with my logo, converted in 3D, rotating 360o (like Earth). The logo should be converted roundly (but with its own analogies). I want it to put it in my work's computers as a screensaver and in some televisions to play 24/7. The colour of backround should be black.I attach the file in pdf.

The final project should be a movie file in hd quality so at the begining the orange "person" be on the front and the green at the back, and through its rotation the green will be at the front and orange at the back with "gap" among them. The length of this should be around 2-3 minutes. All I want to do is rotating, again and again.

The 3d model file should be delivered as well (must be able to open in AutoCAD or Photoshop or Illustrator).

I want it as simple as it can be. Without special effects, without music. Just the 3d logo rotating slowly (period 1 rotation in 3-4 seconds) in black backround. It must be relaxing.

The shape should be like "the gherkin building" in London (England), with rounded edges and "hollowed" inside (or like an egg). All the "persons" must connect each other like the 2d logo (hands, legs) in order to achieve the feeling of continuity (attached image).

The time limit of the project is around 15 days (must be ready on 15th of April.

Feel free to ask anything you want. Please make offer only if you are sure that you can complete it.
Ideas for the visual style: As described above
Preferred colors: Colors of the original logo
Extra notes: Preferred deliverable files:
- 2-3 video files (same but in different formats, for example .mov, .avi, .mp4) All in high quality. The video will be play in 48'' tv as well.
- original 3d model (prefferably could be opened in AutoCAD, Photoshop, or Illustrator)

The acceptance of any offer will be after 31/3 (tomorrow).
