$300 - Flash intro design for new 2.0 site

This contest is for a very short flash intro for a new site that has not yet been released. The intro will illustrate a very general "how it works" demonstration.

Accepted File Formats:
FLA, PSD

The site will be an Online trading/marketplace. Target audience will be similar to eBay buyers/sellers. Since this site has yet to be released, very few details can be given regarding the details in this stage of the contest.

Screenshot of website:

Please see the example storyboard I have made:
http://208.72.2.237/CSSThemes/howitworks.asp

The flash intro will be added in the blue place holder (515px X 320px)(color can vary). The intro does not require any sound.

The "how it works" diagram should be similar to:
http://www.authorize.net/resources/…ksdiagram/
I used the diagram as an example of how the arrows and the steps work. The content will be completly different than the example given. Our site will require 5 steps total. If you wish to create a mock-up, please just use "step1, step2, step3...etc.." with some 10-15 word filler text explaining the steps. Sorry for being so vague. Since this is a start-up site, we are very careful about releasing any details before the site is actually released.

Please see this image for a design concept:

Please provide a 'mock-up' flash intro using the limited information I provided. The contest winner will be provided with the full storyboard and text details for final design.
