Foundry makes 28MM "Street Violence" Figures.http://www.thewarstore.com/foundry28mmstreetviolence.htmlThe line has everything from Swat Teams, Mobsters (Of Italian, American and Japaneses variety), Gang Bangers, Civilians, The A Team, Skin Heads, Slashers, Cops, Hooks, S&M "cults", and every off the wall out there underside of humanity that ever existed or was ever dreamed off.
I do not know how they would stack up next to GW's 28MM Heroic. But may work. (I been thinking of useing real 28mm for gaurd's men, what why the SM will acculy be taller then my gaurdsmen! >__O )
All figures are pewter and in packs of 5 for $19. Also scroll down to the bottem and grab the rules for the game anyway. The rules are a free PDF they E-Mail to you, and since you will have all of these modles, might as well try out the wanabe Necromuda game they go to.
XD
Also if you like/don't mind the scale of the modles, cheek out the "STREET VIOLENCE MOB [50 models]" 50 modles for $150. This deal saves you $40 compared to buying them all separately.
After writeing this up, I found this web sight. http://www.weetoysoldiers.com/wp/?page_id=183.

A cheeper option is the
Pig Iron. There thows guys who make the heads but they have a minature line, a Pack of 5 for $15 (and comes with 5 extra heads.)
These will be the same size as a gaurd's men. Thow I think the Foundry Street Violence figures are exactly what your looking for.
Edit:
Copplestone also has two lines witch will intest you.
Future Wars:

And the limited 1930's Ganster Lines you could mix in.
