Design a Poster for a Mobile Ordering App

I require a poster (a4 or larger) to go on the walls/doors/windows of shops that have partnered to use our mobile ordering app. The primary aim of the poster is to catch people’s attention, make them realise that there is a better way to order and to download the app. The app is aimed at busy people who don’t have time to queue. It would be really great if the poster can convey the fact that this app will save people time and frustration not having to queue up every day. Poster should include company logo and our strapline (both will be provided to the winning bidder, along with some additional information on product benefits) Should also include the companies web address Should include the App Store & Android marketplace icons. Could also make reference to a web ordering portal if you can make/design a matching icon I'm after something really high quality & inspirational so please do not bother bidding unless graphic/poster/print design is your speciality. I will be checking portfolios/past work in your profile so please ensure there are examples of this type of work.
