Word Templates and Forms Help

I frequently create contracts and related documents for various projects and transactions in which I engage. Typically, these require me to identify a number of fields (borrower, buyer, landlord, etc.) which are then used throughout the documents. The documents are not very complex, but can sometimes be lengthy. Currently, I create these types of documents in Adobe Acrobat simply because I was able to figure out how to do it there. But Acrobat is not ideal for this use, as it makes the document text harder to edit. I would like someone to help me design some of these and teach me how to make them (so I can make simple versions as I need). I'm attaching an example of the Adobe version of one such project here as an example. Can you show me how to build something similar in Microsoft Word?
