Hi bbydino,
As Mike says, you need Sketchup Pro to export in the right format, then you need to buy Deep Exploration, and both are extrememly high priced. Not Worth it, Unless you're going to use your models to bring money back in. You'd never make up the money you'll spend on the software unless you're working with a company, or something like that. But even then, they'd have all that anyway. And you'd need to be producing top quality models.
On the other hand, you could search around a bit for someone that would kindly convert a model for you.
Jack.
