Create a fillable PDF from Word document

Hi there, thanks for your interest in this project. I just have a 3 or 4 page questionnaire that I am creating in Word, that I would like created in a PDF form that users can fill out, save and send back to me digitally. I will need to be able to edit this document over time, and I have Acrobat Pro 9, so please plan to provide a few instructions on working with the file after you have created it as well. Thank you in advance, I look forward to hearing from interested parties soon!
