Where can I find save files from other users?

Hello.  I thought this would be a slam dunk but from the lack of hits in Google I suspect it may not be as easy as I had thought.  I would like to find a PS3 save file for Soulcalibur IV with everything unlocked.  I plan to eventually play the single player mode but, in the meantime, would like to have all characters available to play with others.

Is this an impossibility or somehow a taboo subject?
