You'll have to work with a reseller. It's a bit of a pain, but it's not too bad. I've used Dell and CDW in the past. The minimum volume license buy is 5 licenses. Any good reseller will sell you 1 copy of LTSC and 4 of the cheapest SKU in the catalog (usually $5-10 / ea) to get your volume license contract started. After that you can purchase piecemeal for 2 years before you need to fulfill the minimum purchase again. The licenses themselves are perpetual. I don't like it, but it's not too hard to do either. The trick is finding a reseller who will leave you alone after the purchase (no sales calls, etc).
