Animation for and Athletic Club's logo

We want to make a logo animation for our Athletic Club Here is the scenario The screen is black(16:9) A gold seed is born in the middle and in medium shot, It goes back to a long shot, and as the seed is traveling to diagonally left back, the sky is turning blue(28489a - HTML code) and the ground appears also. The seed gets to the ground and from there, an apple tree appears gradually from where the seed had fallen. Simultaneously, some leaves are sketched on the ground and a few small clouds on the background sky. The tree is full of apples (like the ones of our logo) and in the right corner progressively appears the yin-yang logo. The shot is zooming in the logo, as the tree and everything else disappear. The logo is sketched, or typed, and the sound of a sketch drawing is used when the subtitle is written Duration 18 seconds! Everything as more elegant and realistic as it can be. Send me portfolio and demo through PM. Also send me how how many revisions will i have for the animation. Some minor changes in the descrition will be made on the road...
