Create a Microsoft Word and PDF Form

I have a PDF which is basically an image right now and not very high quality. I would like the document created in Microsoft Word as a fillable form (which I can edit later) and also as a PDF fillable form. The document feels a little cluttered to me and difficult to read and often ends up with fields missed. If anything could be done to make it more user friendly, this would be great. I have attached a copy of the document here.
