Looking for someone to write a script for me

I am an Attorney and have many PDF files. I attach a watermark to my PDF’s wherein each page there is a side-numbers running vertically down the page 1 to 55. So basically, I use these side numbers to identify where in the page there is a relevant sentence. What I would like is the following… and I would be willing to contract with someone who thinks they can accomplish such extension. When I select-highlight text from the PDF and it is placed in the mindmap section, I would like a a tag with the page number and the approximate side page number to be added to that block. Anyone think this is doable for a reasonable price, please let me know. Kershekm@gmail.com
