Welcome to Librarium Online!
Okay, since I don't feel like throwing all of my money away buying blisters of grotz, would a regiment of converted goblins from WHFB look appropriate? I mean, they look relatively the same, so I would assume they would work out. I could probably cut off the spears and replace them with some gun bitz, then buy some circular bases and glue them on. Are there other minis I don't know of that could be used? Maybe I am old fashioned, but I feel that paying $80 for one full grot squad is a little steep!

Not old-fashion in the slightest (although looking at the goblin thingy I think you only net a 50 cent save between them and a normal grot).
I'm not on my usual computer, so I can't hook you up with the URL I came across that deals with converting gobbos into grots. When I get back to my dorm, I'll see what I can do for you.
As for grot blastas, take a look at some of the gun sprues from the classic range, or cut the barrel off of a slugga and a shoota. Stick the slugga barrel onto the shoota handle. Presto, a rather weedy looking gun. You can then proceed to combine the shoota barrels and slugga to get some interesting sluggas (I use these for my skarboy and 'ardboy mobz).
