Adding a barcode to product text based on a productnumber

I have looked at teacup pluggin patternmaker and it is definately the easiest way to quality control and if necessary update files.
What I miss is the ability, though I would guess it is scriptable to search and replace a series of serial numbers with a specified character style, or with a GREP search, with barcodes (In my case Interleaved 2 of 5 with no Check digit)

(A barcode font would work as well if it can append the barcode on a new line at end of paragraph)

eg.
"1x100 3:99/each 299:00/box
  999999 product information"

with:

" 1x100 3:99/each 299:00/box
   999999 product information
   "barcode representing 999999" "

I imagine that the barcode would be an anchored object, anchored at the number (in my example 999999 ).

So i would need to figure out a script to copy six digit numbers after a line break,
replace them with an anchored frame and itself
that anchored frame would then need to be filled with a barcode of the copied number with a certain preset.

I don't think I am asking the impossible. But I don't really know where to start. My job is as print service provider and so I am open to outsourcing the develoment of such a script if ther is not a solution for it already.

Sorry for being so overt, please feel free to comtact me off forum for a suggestion
