Are you kidding??? You guys down south have some the greatest wrecking yards in the country! Get the phonebook out and look in the yellow pages and going in person!! There should be an area where there are a bunch of them in one area. The wrecking yards have plenty of stuff that is that age or newer!!!
You can check LKQ, although I'm not sure they are in your area.
The bumber should cost you about $100. I swear, if you look you will be able to find one. It's fun to root through the wrecking yards too, the people are a hoot! Nothing like seeing a dude eat french fries with half a hand, covered in grease, picking his nose, and petting an old cat all at the same time!!
Oh, ya...check Craigslist.com too!! http://www.lkqcorp.com/home/home.asp
