Header Images for a Gaming Website

I require six 1000x120 header images for an online gaming website. Each image will represent a category of games such as racing or soccer.

All images should be made using screenshots and/or any artwork from one or more flash/shockwave games.

Here are a couple of samples of what I'm looking for:

The winner will be awarded $450, which comes down to $75 per image.

Here's the list of categories and a few sample games. Don't limit yourself to these games only, there are literally thousands of games out there that can be used for this, just make sure you write down what games you used for each image so they can be added to the website later.

1. Cars/racing

The images should simply look slick as to motivate the visitor to browse through the games. There's no need to submit all of them at once, 2 or 3 is more than enough for me to give some feedback.

There's no need to add any text or effect to the image.
