I expect I'll be saying this a lot as the Hobbit brings in new players
You'll get further if you provide a list of your own and ask for comments. It takes time to make a good list. I'm not sure about other games, but SBG isn't one where people have *the* list for a faction at a certain point level, there are a hundred ways to skin this cat.
That said, Fiefdoms is mostly metal/finecast, it's going to be pricey unless you proxy/convert almost everything. If you're going fiefdoms centered on Dol Amroth, Imrahil is a must because his banner effect is huge. After that, they've kind of taken some of the punch out of Fiefdoms with the change in the Kingdoms of Men book. Also, with the new Hobbit rules, pikes must back up pikes. So you can no longer make a "ranger sandwich", i.e. backing up foot KoDA with rangers and then men-at-arms. And the BV archers you can take aren't allowed spears.
You could make an uruk-hai-of-Good army with Imrahil leading KoDA backed by multiple ranks of men-at-arms, with some BV archers to provide missile support. Between pikes and Imrahil's banner that would be tough to crack, but the BV archers aren't great IMHO. One cat skinned.
If you don't center on Dol Amroth, Imrahil's potential is wasted, so you might as well stick with the other fiefdoms heroes (Forlong and Angbor), and to get to 1000 points you'll want to ally with someone else. Too many options to consider here, you're really best off picking the models you like and building around that, I don't hate cats enough to skin them all
