Converting a .pdf file to a word file, with some formatting changes

I have a reference section of a book in a .pdf file that needs to be converted to a word file. There are a total of 18 chapters and three appendices with references. I also need some reformatting of the text - like changing " to «, and removing periods at the end of article titles. The document is 36 pages and in English. It is essential that the word document is a normal word document format - and that the spacing between letters is as in the .pdf document.
