422912 Graphic file for header

Hi I am looking for someone to create a graphic to go at the top of a forum site. The image will repace the current logo, however I would like it to go the entire length of the header The image must be on a transparent background so the color of the website background shows thru The site is for people over 50, so I would like the file to have several images in it, \\I do not want pictures of old people, at 40 we are not old. Maybe a few pictures of people doing activities. Please provide me a mockup with your watermark on it I have attached the curent file, It is the right height but not the right length. You will also see how it is on a transparent background I will not select you without a mockup The site is [login to view URL] Thanks
