Create a 1-minute product introductory video

We're searching for an appropriate person or team who is able to create a 1-minute introductory video of our product, which will be on youtube or any other media. Simpler is better, but too simple is the worst. Please let me know if you have a skill to manage this video making and editing. Our web product is not live yet, but we will finish its development soon in 2012. So this video is just for introduction of how it works, based on our product summary and mockup designs, and simply animation-based. Intuitively I'd like it go like these examples below: # 1dollarscan [login to view URL] # Bookscan (Korean) [login to view URL] # Kogan Lifestyle [login to view URL] The first two are stick-bar character animation and the last one is written animation on a whiteboard. Either one is good, but please let me know which type you are good at and what kind of similar samples your portfolio has. Hope your reply will be back soon. Thanks.
