$1000 would probably include sourcing the car costs but that's hardly the most crucial part of the process. I would say most of the work comes when the car lands here in Aus with clearing customs etc.
I wouldn't suggest trying to organise it all yourself. Especially since you are so unsure of the process. It's a recipe for disaster.
Email the guys at iron chef and I'm sure they would be happy to provide you details and costs.
