I helped a friend bag his PT Cruiser. It wasn't a hard job, no more than replacing the struts and running a few air lines.
Air Ride Technoligies is the company he got his parts from. They could also direct you to a dealer where you could possibly get good prices for your aplication. Ask Dean as well, I'm sure he can give you some good info. I've also considered bags, let us know how it turnes out.
p.s. I'm watching an episode of Trucks! where they are bagging an S-10 as I type this.
