Create Website Demonstration Video

I have a new website. I would like a coder to design a video demonstration of the site. I realise you will not be able to bid yet before more details are provided, but this is what I am looking for. - A demo of the main features of the site - How to create a profile on the site - How the site work can benefit you I don't need sound on the video. The video will be about 2 minutes long (I think). I am only interested in hearing from coders that can provide me with a portfolio of videos they have created previously. They do not need to be website demo videos (although that will be a bonus) but should be well designed and created so please only bid if you have a good portfolio.
