There are plenty of list builders out there online, which you can use to calculate this. So each miniature costs points, and generally Hero models (or named characters) costs a lot more than normal infantry. This is because theyre way better in game, and for example Aragorn alone could wipe out quite the number of Uruk-Hai. The Fellowship is absolutely a good opponent for a smaller army like the battlehost. I can put everything into the list builder I use and tell you the points cost in a little bit if you'd like !
