I need a 30 second instructional video for a new start-up

Completely open minded for style but is has to convey professionalism and trust... I truly welcome creative suggestions!!

The website is a social network for polling and debate. It's a completely free tool for society and I will be spreading the word far and wide. It is a great opportunity for exposure for the right person!

Please reply with a portfolio of your recent video work..

Finishing touches are being made to the site but I'll be ready to commence work on the video next week
