CONVERT EXISTING WORD 2007 BOOKLET INTO AN ADOBE INDESIGN PROJECT

I have a completed 80 page (letter size) brochure, of which four pages are the cover, completed in Microsoft Word. I want this to be re-created in the technically best way in InDesign CS5 ready for my additions and amendments. Importing straight into InDesign is not acceptable; the brochure should be recreated from scratch using the existing text and images and based on the current layout.
