READ please. Looking for a 3D designer capable of making a realistic video animation for a secure communications product

Again, read first please BEFORE accepting and let's not waste time. I have written important details here which will make you understand whether you are fot for this task. I am ready to start asap - with the right person. You need to have some experience and showcase me some work you have done. I need a moving animation which I can put as a background on my webpage where I showcase my company's product. I have a full specification and a little sketch which should explain further of what is needed in that animation. My company sells the most secure telephone on the market and this animation need's to showcase visually it's portability capabilities. It need's to be a very realistic rendering. The main object in it is earth, zoomed in to some extent and slowly spinning. On one side of it we need to place a satellite which has beams to multiple objects on the surface of the earth. These objects are representing different users in different locations like desert, jungle, sea, urban - etc. Because it need's to be a realistic looking sci-fi level 3D rendering, we need to ensure that objects are at a realistic scale. Meaning that a person on the desert can't be 200km tall according to earth scale just so that we can see the person from our viewport which is from space. We need to perhaps use some intelligence zoom capabilities as used in some mission briefings in modern war games or sci-fi/action movies. Or perhaps you as a designer have a better suggestion? I have a sample of this idea on a sketch which I can share. Please answer these questions: 1. Are you good in 3D animation design? 2. Can you show me few of your best 3D moving animation designs?
