Simple design job for homepage graphic

Dealerhound.com

Our site is a listing service for new car dealers in the United States who want to trade cars with each other. They post the cars they want to trade to other dealers. They can also look for the cars they need. Once they've found them, dealers can arrange shipping. We want to keep the site simple, clean & professional. I think we've achieved that, but the homepage content is too wordy... I'd like to replace it with a professional graphic that explains our function.

Our users are new car dealers in the United States. (Honda, Chevrolet, Toyota, BMW etc.)

We need a professional graphic that explains the three things we do. Right now we have two paragraphs of text for this purpose, but a nice layout showing them is much better. This needs to fit at the top of the content section of our homepage at http://www.dealerhound.com.

The three functions of our site are:

1. Search Inventory
2. Post Inventory
3. Ship Inventory

Here's my failed effort attached. I need a professional to take over from here. Be creative, flash or html 5 is OK but not required. The key is to communicate our function the user. I will be very responsive to your work. I want you to win, so talk to me.

Additional suggestions:

a) Try and mostly use our site colors
b) Three icons for Post, Search & Ship might help.
c) A fading slideshow for the sales points might be a good way to keep the design from getting too complex.
