Photoshop image illustrating a collaboration between two companies

I have four images (two logotypes, one photo, and one app screenshot) that should be combined into a banner image that illustrates the collaboration between two companies. The logotypes should be above their corresponding respective photo and screenshot. I am thinking that the logotypes should be as is, and that the photo and screenshot should be arranged in a slight angle facing each other. Also, please make a slight reflection below the photo and screenshot as illustrated in this image: [login to view URL] The finished image should measure 1,200 px in width, and 600-700 px in height. Please get back to me should anything be unclear, and I will try to clarify. Thanks!
