Concept Building for a Video for a new Project and Raising Funds in Kickstarters

I have a bunch of new products in that are almost ready to hit the market. I am looking to make a video for the new Products to Raise Funds in Kickstarters and Similar websites and also for marketing the Product. Utmost importance would be given to the concept of the video. The Freelancers who are interested can send a Proposal with a Rough Concept for the same. Once the Freelancers Signs a NDA, I would reveal you a similar video and the Product Details. At the moment we can only say that it is the next level of Stick notes and Whiteboards. The Freelancer would have to send a Rough Concept, and also share their work. The Project would be given to the best concept.
