Build a Website

Build a simple Facebook App that takes some existing PNG's, according to button clicks by user, and creates a new combined PNG that is then shared on the user's wall. The UI/UX is already done, just need the designs to be created in HTML. Tasks: Create screen for user to pick from 16 "Base" pictures to be applied to the canvas. User is sent to second screen upon clicking a picture User then has 6 buttons that reveal 3 different png options (total of 18 components on second page) which are overlaid on the base picture at predefined x/y coordinates. User needs to be able to remove elements from canvas by clicking on them (Is this possible?) Once completed, user clicks button which will create image from canvas and share it on their page along with a custom message that they can type. All of these screens have detailed PSD's available, but they will only be available once a bid is successful.
