create a postcard graphic for marketing

I work for a software company and would like to send out a Snail Mail campaign. I want to send a post card attached to some popcorn. Side one: "I know this may be CORNY, but I just wanted to POP by and say good luck with the upcoming school year." with popcorn all over and the company logo off to the side. Below I would like my personal information for the prospect to be able to contact me. on the backside, I would like our product wheel to be attached.

I am looking to send this out within 2 weeks.
