Chaos dwarfs are pretty easy to make. I got my old dwarfs(i dont game with them anymore) out of my cupboard and the 40k chaos vehicle bits.
I gave all of the dwarfs blood red trims and shirts. I cut off some of there axes, picks etc and replaced them with the tomb kings' curved swords and put some spikey stuff on them. I have also converted a Lord and made a few rangers into blunderbus guys. Its a very effective way of doing it.
I am planning on getting some goblins and turning them into hobgoblins soon.
Hope this helps someone...
