Swishmax or Flash Pro for short animation clip

I need to put together a short (3 minute) flash presentation that will be used as a software product presentation. No sound is needed for this. Just clean graphics, animation and timing (as narration will be added after). Basically, I need someone creative who can take some images, reconstruct things and animate objects/text in a dynamic way. I'm only interested in those who provide me samples of similar work completed. Big preference given to US based programmer who can be available via phone, as I strongly wish to discuss my exact needs over the phone for this job. I have no interest in previous work that is not related to this so please don't send me links to portfolios, sites, etc... And finally... I make no payments upfront of any type! I pay in full upon successful completion. If this is not acceptable to you, please don't bid.
