Animated video production (explainer video) - open to bidding

I work for a company called [login to view URL] and we would like to create a explainer/marketing video for our linkedin, facebook, twitter profiles and generally to be part of our email marketing efforts to send people to explain what we do and why we are unique. This video will help explain what we do, who we are and why we are different from products and services. The video should be about 1 minute long - I quite like the look and feel of [login to view URL] but am open to suggestions and improvements. You must be able to show a portfolio of similar projects delivered and be specific as to what you need form us to help you deliver on time to budget. The people who will buy our services are high street retail marketing teams who want use mobile as part of the marketing mix. They will be UK professional marketeers so quality and language needs to reflect their profile.
