So many options

A quick Google search will return a bunch of options for converting a .PDF to a word file. I use www.convertmypdftoword.com because I knew and trusted the creator. I haven't needed it since he sold it last year. There is also CutePDF if you prefer a download.
 
There are tons of cheapos out there but if you're serious you'll get something with good OCR; you really do get what you pay for.

My fave is Acrobat Pro XI, but I'd say Abbyy Finereader is a good one as well, perhaps a bit better in OCR but maybe not as versatile for some PDF specific features.

If you just have a PDF, use an online converter. Abbyy even has one through Facebook I think.
