Need 3D Sci-Fi character models for game addon...

Does anyone know if/where I can find the following characters/species? I know it’s a huge request, but I need them:

Stargate:

Asgard (Grey-like species, any character will do, they all look the same, since they’re clones)
Wraith (preferably Todd or Michael)
Replicators (bug and/or humanoid forms, especially Fifth)
Goa’uld Symbiote (adult, not juvenile)

Star Wars (There are plenty of SW character models out there, but I can’t seem to find the following):

Momong (Monkey-like creature from Clone Wars)
Fosh (Vergere) - I know I requested this one a while back, but there has to be a model out there somewhere…

Star Trek (Even if they’re the models from Star Trek Online, any will do.):

Romulans (especially Commanders Suran and Donatra, preferably in those poses)
Bajorans (especially Kira Nerys)
Klingons, (especially Worf and Gowron) So far, I’ve only found ships and weapons.
Ferengi (Quark, Rom, and Nog)
Jem-Hadar (any variety will work)
Vorta, especially Weyoun
Cardassians (especially Gul Dukat and Garak)
Suliban (Cabal leader Silik)
Denobulans (Dr. Phlox’s species)
Changelings/Founders (I’d prefer Odo and the female Changeling, but I can’t even find models of them in humanoid form)
Xindi (Any species will do, but preferably the Primates)
Remans
Trill (Dax symbiont, Hosts: Jadzia, Ezri)
Khan (from Into Darkness, not Star Trek II: The Wrath Of Khan)

They’ll be put in the mod as statues, drivers, still life renders (TGA), etc.

Model formats accepted: blend, obj, 3ds, skp, xna (.mesh), nif
Price Range: Free only, no paid models.
