MS Word : Macro/VB based form creation

We have a postcard design which needs to have certain parts editable in MS Word 97/2003 - this is achievable with forms - however, we also need the user to be able to browse and insert an image, which will be automatically resized to fit the postcard correctly. The postcard is to be replicated and printed out 4 times on an A4 sheet, the sheet is to be manually turned over and printed on the back. We have produced a near working version but its not right and we need someone with excellent MS Word/VB/Macro skills to rework it or if necessary redo it completely so that it works flawlessly for us. To recap, the postcard is double sided, the user enters their details and photo onto a template, ensuring content to be included in the reverse of the card is also included - and then at the press of a button the document is replicated 4 times to fit an A4 sheet, the sheet(s) are then removed from the printer, turned over (users responsbility to ensure they put it the right way!) and the reverse printed, i would suggest at the touch of another button. Questions welcome, as are alternative methods of production.
