i'm totally drawing a blank here or i'm just thinking too hard but please tell me or explain what are document designs and where can i get them and this is for business thanks
Document designs must be referring to how various documents are set up -- how a business letter is set up differently from an interoffice memorandum, how a resume is different from an invoice, etc.
You can get templates for all sorts of business documents. If you are using Microsoft Office, many are available within the program (go to File | New and a Templates section should show up in the right-hand column), and others are available via http://office.microsoft.com/en-us/templates/default.aspx
There are also websites like this one:
Scroll down until you find the type of document you want, and Purdue's website will tell you how to set it up, etc.
