Exporting FCE project for colour grading

Hi Folks,

I have a complex 3 minute video, edited in FCE, that I now want to send to a professional colour grader and am wondering what is the best method to send to him?

The video has many split screens and I imagine he will want all of the shots separated on separate tracks for grading, this plus all of the corresponding split screen mattes. At the moment all of the files are on a 4t external drive, so I guess I will have to buy a separate small drive and copy all of the files onto it.

Any suggestions much appreciated.
