I need a pop up for a show designed

Design details: I need a design for a pop up which we need for an exhibition. The pop up will be the below sort of shape and i require back the design in PSD format as well as a mock up of how it will look.

I would expect there to be several iterations prior to sign off. I need this job completed quickly.

I will only use people who have good examples of previous work.
Ideas for the visual style: its promoting our site
Extra notes: the 2x3 version below is the shape of the pop up we want.
