One thing that might work is using a program like PDF to Epub. They had a period where they were offering it for free not long ago though that may well be over now. I'm not sure what the program costs but it can convert PDF files to HTML, epub or Kindle directly. No working TOC with the file if you convert directly to Kindle as far as I know, but it may work. The only thing is that it's a one at a time conversion so if you have a number of PDF files to convert it may take a while.
