Hi,
I specialize in creating custom-made tools for PDF files, especially using PDFBox, so I believe I can develop this tool for you without much problems, but your stated budget for this task is not realistic. You won't find anyone serious that will do it for less than a $100, and that's before seeing the actual file... If you're willing to be flexible on the price we can discuss it further.
I can do this for you quickly and professionally, and I'm available to start working on it right away.
A little bit about me: I'm an Expert on both the Adobe and AcrobatAnswers forums and have a website dedicated to my custom-made tools for PDF files that you're welcome to check out (Google my handle-name to find it).
You're also welcome to check out my work history on this site and see some of the PDF-related projects I've worked on in the past.
Regards, Gilad (try67)
