You could open a new document in Word, but before physically opening it, check the Template rather than the Document button in the bottom of the Opening Window.
Then insert your Logo and other details and insert a table of one column width and as many rows as you want to fill an A4 sheet.
Then save the document as a template with a suitable name.
Every time you want to open that document, go to File/New and click the Template you have just saved.
Hope this helps.
