Do you have ideas as to how you might want to organize your army? If you want to have both Dain and Balin, as well as some Iron Guard this is a rough draft of something you could work with, I'm assuming your looking for a
LoTR army not a
WoTR army:
Warband 1: (215)
>>Balin, Lord of Moria + Durin's Axe (95)
>8x Iron Guard (120)
Warband 2: (245)
>>Dain Ironfoot, King of Erebor (125)
>8x Iron Guard (120)
Warband 3: (173)
>>Dwarf Captain + Shield (65)
>12x Dwarf Warriors + One Hand. Axes + Shields (108)
Warband 4: (173)
>>Dwarf Captain+Shield (65)
>12x Dwarf Warriors + One Hand. Axes + Shields (108)
Warband 5: (193)
>>Dwarf Captain + Shield (65)
>1x Standard Bearer (38)
>10x Dwarf Warriors + One Hand. Axes + Shields (108)
Total Point: 994

I dont have any experience with dwarves, this list is something I pulled out of nowhere with the rule book and the warhammer website, so I suggest you look into adding some dwarf ballistas and maybe a dwarf champion and in exhange make some changes to some of the warbands. I would have added dwarf rangers, ballistas, the a champion though I couldn't find the rules and point cost. If you have the khazad-dum supplement you could find the rules for those units and see to incorporating those into your army. Good luck with it
