I can't afford it sir, thanks again.
You might check the option to purchase 1 year subscription for Acrobat XI Pro(Link below). Acrobat is a complete PDF solution, it can help in exporting the PDF to word even you can edit your PDFs in Acrobat itself if you have to some minor changes.
Click subscription(Not upgrade or full) if you are planning to buy
