It has been my experience that while almost everybody can create a passable document in Word, something technical/government-ish with 500 pages and all of the publishing accouterments that come with a document of size, purpose, and complexity, you're getting into specialist territory, and almost all of the DTP specialists I know start by importing Word files in to InDesign.
