Create exciting <1 min promo video for local directory site

Hi world! We are showing our website at at local business Expo this weekend. We had the idea to produce a short animated video of our site that we could show on an LCD screen in the background, and then later incorporate into the site. But dont have time to prepare it ourselves. We are seeking a creative person that can work fast to put together a promotional video of our website showing off it's main features. Some screen grabs and highlights of the main features with a bit of text on top. A few professional and exciting animations that bring the page to life would be nice. No need for voice-over, and background music optional. Budget is tight and so is the timeframe! Is there anyone out there keen to give it a try? Some samples of any similar work would be good. Look forward to hearing from you. Website is [login to view URL]
