Invitation to academic discussion dinner

We are seeking a very quick turn around (2 or 3 days) for a simple event invitation to an academic discussion dinner. It has already been designed by a colleague who is not a graphic designer, and we'd like to see if it can be redesigned to look more grand, prestigious and striking. InDesign file can be provided. Guests will be HNWIs. It carries one image, two logos and some text and would be produced as a PDF to be emailed, not printed.
