Cut, Crop and Transparent Backgrounds for Logos that are already made

I have 500 files. On each there are logos (logo elements). I need each logo to be cut out, cropped and given a transparent background (alpha channel). Then named something like [login to view URL] , [login to view URL] , [login to view URL] and so forth. If the logos on the particular file are a little too jagged then it will require a guassian blur. If the individual logo is way too large then it require to be resized to 400 pixel width. Each file of the 500 contains anywhere from about 10 to 40 logos on it. Most contain something like 15-20 logos on it. I uploaded some files to show samples of what Im talking about. Before and After. Most files come in either .eps .ai or .jpg formats.
