Hi,
I specialize in creating custom-made, stand-alone tools for PDF files and have developed various tools very similar to what you describe. I also have experience with RTL languages (Hebrew, Arabic) in case you want to include text in your native local language.
I can do this for you quickly and professionally, and I'm available to start working on it right away.
We will need to discuss how the tool is going to be used, though, as my tools require Java to be installed and running on the local machine...
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)
