3D animated video intro (5~10s) with sound effects for Youtube / Vimeo clips

I'm looking for someone who can make a 3D animated video intro with sound effects, using our company's logo. We want to use it as an intro for our tutorial we are going to place on Youtube and Vimeo. Our ideas (to be discussed, own ideas are very well appreciated): - Duration of the clip: 5~10 seconds, to be discussed. - Full black background - Our company logo has to appear as falling from the top of the screen towards a matte or dusty surface - It should land hard blowing away some dust and uncovering a glossy surface beneath it - Falling logo should be reflected on the surface it is landing on - It's important that the physics look real - It needs to look classy and robust We will provide you with: - High resolution artwork images (.png and .svg) - Fonts You provide use with: - The animation with sound - All artwork still you generated in the process - All sound clips generated or used in the process
