Open PDF - extract vectors from pages to EPS files

I've got an issue where I need to batch process around 100 PDFs (up to 3-4 pages in length) where I need to extract the vectors in them, and save them to separate EPS files.

We are re-building a database with the images.

What I was looking at doing was using an exisitng script that opens PDFs and creates artboards for all the pages.

Now for my script I was looking at using the PDFs filename to create a folder (that much I got going).

What i need to know, is if its possible to now using the selection arrow, copy and save the selected area as an EPS?

I could probably do this with an action, but i was using a script that would look at the filename, add a suffix like "1" ... then "2" as I select and save the vector.s

One of the things I as thinking was to have an action trigger when I selected the vector, copy it to a new document, resize the document to the selected size, then save the vector as an EPS with the filename and suffix.

One of the issues I have is creating a new document. Can someone tell me how to do that given a name (filename+suffix) I want to use?

Is there an easier method that I am totally overlooking?

Many thanks in advance for any advice.
