Video creation for website introduction

We are looking for a video editor/creator that will help us create 2, 60 second video presentations that are aimed at the user and the other advertisers. They will need to explain the purpose of the website and benefits to the user and advertisers, also giving a brief overview of how to use it. This will go on our landing page and YouTube channel.

The videos will require a few effects and intro animation (including logo). Information on our product will be provided for you to create a script and voice over.
