These links should help (USA info/pricing): I think the academic/educational offerings require some kind of verification, and that may not be possible in the timeframe you've been set :( There are some academic/educational offers available, there is Office 2010 University (for Windows), and some institutions have student/staff offers available. Office for Windows, and Office for Mac, are separate products, and they are not bundled together.
