31137 Create graphic/header photo

Hello. I just attempted to create a header collage for my new website. You can view it at: [login to view URL] I am not a designer and I don't think it looks clean and professional enough. I will attach the photos to this so you know the size I need (must be exact same size as the header photo on there now. I will also attach the additional individual photos for you to use. I really need MOCKUPS and will only choose someone who provides me with them. Thanks.
