GRAVITY product explanation video

We are a small startup based in Zurich Switzerland. We created a system to replace e-learning. Out of that concept we developed our first product, called Gravity ([login to view URL]). We want a video (about 2:30min) to explain visitors of the web site very fast what Gravity is all about. We would like to have people look at the video first and then react to it. Either in reading more information or get in touch with us. Our visitors are IT- and HR-Guys or CIOs of enterprises.
