Demo Video Tutorial

I'm looking for someone to create a few video tutorial/demo tour for my new web-based application (graphic design tool) The purpose of the video is to obviously explain how to use the program / explain all the features and how to use it, etc. Requirements: - I need each video to have an intro including my logo and the video title. - Prefer Female voice - These videos need to be high-impact, visually appealing tutorials - as such you may want to add some flash effects, zoom, etc. - Prefer someone who has design skills To bid, please send me a link to a previously created video tutorial. Thanks
