Edits to PDF Generator (css, js, html) . ..

Our company recently had a PDF generator built for us here, on Freelancer. We are in need of some edits and revisions but the original freelancer who did the work is unavailable. The pdf generator is a local html application that runs on our computers. It was built with css, js and runs in html. Most of the edits we are looking for are simple ( font size changes, renaming certain headers, etc), but the most important one is having text editing options added to the current text boxes. If you are interested in the project, let me know and i can get you the file to take a look at. Thanks
