Animated Video to explain how the website works.

Hi, We need an Animated Explainer Video(Should include voice also) that explains how our Website works. Since its a startup company we want to keep the production cost low, but still be able to provide a good quality video. If it works out we will need more video's in future. I need professional people to take this job with good communication skills. You need to provide me documentation before the project starts, which will give me a brief idea about the output video. Also while bidding please give me all the information both technical information and designing. I need experienced and creative people to take this job. Please refer these video to get a concept.
