Design for Postcard size flyer

I have a simple double sided design project for Postcard size. I have all files ready (2 logos and 1 background vector image). Text layout mockup done in powerpoint so you can see concept idea. Text ready. Just need it too look more professional. Layout and look and feel is where you will add value. I have specific standard fonts as well. I am in need of a quick turn around (project finished within 48 hours including retouching if necessary). Files i will need you to produce will be eps or equivalent for printing at professional printers. Thank you.
