Someone please tell me where to get 3D models of these characters!

I've been looking everywhere for these models. 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):

Beru Lars

Cliegg Lars

Owen Lars

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)

DC Comics:

Richard Dragon (Enemy of Green Arrow)

Jor-El (Marlon Brando version)

Model formats accepted: blend, xps, fbx, dae, mesh.ascii, glm, psk

Rigging: Required.

Price Range: Free only.

Post links in This forum. I'd prefer the models to be uploaded as Fan Art on Blendswap, or as an XPS, FBX, or DAE file (with textures) uploaded to MEGA, Google Drive, or Mediafire.
