Graphic design for a postcard mail-out for pizzeria

I'm looking for someone to help with the graphic design of a custom-sized postcard for a mail-out at my pizzeria. I have a general idea of what I would like the design to look like, but I am open to suggestions for ways to improve it. The primary message or offer that I want the postcard to communicate is a promotion or discount offer. The size of the postcard should be 6.25 by 9.
