The problem with LTSC is that it is very hard/impossible to get it legally as an individual. You can do it in unofficial way but that has its own problems.
It's not that hard. Give CDW a call. You'll need to setup a volume licensing agreement, which means buying at least 5 licenses, but there's some $10 licenses you won't use if you need filler. Also, this is an upgrade license, you need an underlying windows license on each PC to upgrade it.
That is a different product. LSTC != IoT LSTC, it is so confusing. To get the IoT you have to sign lots of contracts, Microsoft sends you stickers to put on each stuff, stuff like that.
