Thanks for the pointer. MSDN would cost $1200 for 2 years (https://www.visualstudio.com/products/how-to-buy-vs) which would provide perpetual licenses for development purposes.

http://lemingtonit.com/services/FAQMVLS.aspx says that a volume license agreement starts with a minimum of 5 licenses, but they can be different SKUs, including low-cost ones.
