Is there anything specific you need? Ships, weapons, buildings, etc.? darkness_02 has some ships for sale here, and I know ShareCG has some ships and blasters (can't recall exactly who has them there off the top of my head). If you're willing to put in some work, there's a bunch of SW stuff on Blend Swap (just be sure to read and follow the licenses there).

Be sure to post the video here (or a link) when it's done!
