Simple macro required - ** I can pay **.

Simple macro required - ** I can pay **.  I would like to click on a button on one of the bars which then opens a dialogue box (that's what I call it - it may be called different to you experts) which then gives me the option of presenting me with one of 4 different sized rectangles (A4, A5, A6 and A7).  These would default to portrait orientation but I would have the option to click a box which would produce it in Landscape orientation.  The rectangles need to be just outlines (HAIRLINE width) with no fill.   Can you PM me a quote and ETA
