Facebook Application Poll

Hi Freelancers! I'm looking for a freelance web developer who can create a Facebook tab/application on my clients page. The tab would be a simple polling type application that would prompt the user to "vote" between two images, and then display the current tally of votes from all users based on the percentage of votes received. At the end of the campaign we'd like to show the winning image. The page should also include a share with friends functionality. I've attached a mini-wireframe so you can get a better idea of what I'm looking for. The project needs to launch on 10/15. We'll provide the creative elements and would need coding. I expect to have design approval by 10/10 and we can hand over files then. In addition to the development, I'm also looking for guidance on how to get the app live on the clients page and answer any questions that might come up during the process. Also - I havent done this before so am open to using a template or custom application (or something different) based on a strong recommendation. Let me know if you have questions.
