Maybe a mix of manufacturers and when I say that I mean converting plastics (or even metals) to get the look you're after, head swaps, shield swaps etc.
Guy: I agree with James on this one.
Maybe start with the GW or Gripping Beast plastics and convert away from there.
That is the way my Army of the Dead are going to be done.
If you need any of the various plastic parts/sprues give me a shout, I have a fair few now.

By the way: When do we start?
