I am looking for a downloadable copy of the IBM commercial
that came out a few years ago for a business presentation.
It's the one where a startup dotcom business launch their 
website and they get initially excited when a flood of orders
come...however their excitement turns to dread when the orders
keep coming and they don't know how to handle it.

Any ideas where I can find this commercial?

You can try http://www.adcritic.com/
I know they have a bunch of commercials there.
