Need SQL 2008 R2 Evaluation Version

I know that Microsoft has released SQL 2012 now, but my company wants to move some of old servers to SQL 2008 R2 now. In this regard we are looking for SQL 2008 R2 Evaluation now, could you help where to get the same??

I tried many links but all of them direct to SQL 2012 download :(

Also, if my company decides to purchase SQL 2008 R2 now, will Microsoft will priovide us the license??

Any help on this is appreciated...
