Presentation Animation in After Effects

We need to have a concept mocked up in After Effects. The 5 screens have been completed and laid out in Photoshop layers. We need to have this design now taken in to After Effects and animated with transitions between screen, transitions on image elements and text, and just to make it look over very cool. The current artwork design consists of: Intro Screen, Screen 1, Screen 2, Screen 3, End Screen. So there is essentially four main screens (that the animation lands on and holds) that needs to be animated up to look slick. All PSD's can be supplied immediately. We need this completed ASAP/immediately. Artwork needs to be supplied with After Effect project files and finished video for presentation. We need completed quick and fast. You will need experience constructing After Effects Motion advertising and have a good eye for clean, effective and great looking simple animation. Attached is a an end screen to which the animation will finish on. This provides an example of what we're looking for. i.e.. this background image would transition on to stage, and then the logo would stamp/appear to sign off and finish the 30 second ad. Duration of animation: 30 seconds. Dimensions: To be completed in HD 1980x1080 16:9.
