Are you a student, (should work even without being a student)? If so go to Autodesk Education & Student Access | Autodesk and create an account. Might take 1-2 days, but after that you should have access to most Autodesk products. From there you can download all Maya versions from 2011 and up, then just intall them as trail and when you launch Maya click on buy. Or if you do not plan to release any asset just use the regular 3yrs education license.
