Only for Space Wolves.WTF its 3 hqs at 1.5k points not 1
I've built a Battle Company, from which I draw the majority of my 2000 point army. I'd make sure you've got Rhinos for each squad, as has been mentioned. I'd also look into between three and five units from the Armoury-- Predators, Whirlwinds, Vindicators, and the like. You won't need as many armored units as you might think if you've got a Battle Company present-- the squads' heavy weapons and in particular the Devastators can provide more fire support than any number of comparably-priced tanks that you can bring. Once you've got what passes for heavy armor in a Space Marine army sorted out, I'd look into getting some stuff from the 8th Reserve Company (the Assault reserve) in the form of land speeders. Those little devils are worth their weight in gold. The way the formation reads for the Battle Company is to have two full-strength Assault Squads, so any further units that would be crewed by Assault marines would have to be crewed by Reserve Company guys. Kind of a moot point, but it's good to know when you're putting markings on your models. 1st and 10th (Veteran and Scout companies, respectively) are pretty much optional... you honestly don't need 'em.
The first order of the day is to make sure you've got ten-man squads, though. You can't field the formation until you've got a Command Squad, 60 Tactical Marines broken into six squads, 20 Assault Marines in two squads, and 20 Devastators in two squads.
