Tutorial Video for a website business

Hello I am looking for Tutorial videos for my website. we're looking for someone who is talented and creative to help drive this. The video should be a classic tutorial video showing and explaining the main features on the platform (e.g. register as a new user, entering basic information, choose data that they will report, enter technical data, see results e.t.c) I will provide initial concept, script, voice over and discuss the complete details with you to make sure you are clear on the project. The video should follow the latest screen cast style and shouldn't be a video with someone talking over. Creativity is appreciated. This is the first of many that need to be done. We have other "help" videos planned but want to get a sense of the work required/cost/quality before getting to far into it. Please do make sure to provide your previous work or portfolio for evaluation purpose. I Look forward to working with you. Thank you
