First, get a charity to sponsor. Then contact the local paper in your town about the races you'll be driving, soliciting donations from other drivers whom you race against. Maybe start with drag racing at Island where we have some inside pull for maybe a soundbite from the owner to add to the news article. Great exposure for you, the charity and the track.
Once the autoX track opens in South Jersey, move your racing there so you have both straight-line and autoX experience, sticking with the same charity and maybe picking up local sponsorship. After a season of racing (yes this means NASCAR / Craftsman waits till next year) you'll have enough public exposure and local sponsorship that the pro's can take you seriously. Then seek out the same deal you are looking at now, for the 2009 season.

Is there a faster path beyond one news article? Would they take you seriously with only one or two articles? How much experience do you have? Who are your amature / semi-pro references? Who are your corporate references?
Good luck!
