Recently I bought some dwarfs from my friend's younger brother, because he was never really into the hobby, so I bought them for 50 bucks Anyway so I combined those dwarfs with the dwarfs that I already had from skull pass so I have the following models (I play casually with friends who have no problems with substituting models so I could use some dwarf warriors as ironbreakers or something)

-24 dwarf thunderers (i think those are the ones with guns I am working on getting the army book this weekend)
-2 cannons with 3 dwarfs each
-around 50 dwarf warriors
-16 Miners
-10 ironbreakers
-the heroes from skull pass

Where should I go from there? Remember, me and my friends have no problems with substituting models! How should my army look at 1000 points?
