Poster / graphic designer for comedy show

I require a creative graphic designer to design me a poster for the forthcoming edinburgh fringe festival. I am an up and coming UK based comedy performer. The show is called 'Dirty, Filthy, Rich' - a comedy show about how to get flithy rich and spiritually enlightened.

I will be having a photo shoot this week so will send through images to use. Its a tight deadline - I have to submit the final design on the 25th April.

Here is a link to the brochure from last year - go to the comedy section and have a look at the style/quality of posters.

Please include links to previous work. Previous experience in designing posters is advantageous. I am on a tight budget, so please bid wisely.
