Banner for Website needed

We need a banner designed for our next project. It needs to be free of copyright materials or be designed from scratch in case we need to publish it in other materials. We retain all rights to the graphic/banner designed. I need two versions of the banner. One with our Logo built in to the banner so it can't be easily stripped out and one without the logo in it. Attached is the last banner done and our graphic we need built in. It needs to be stretchable. For example, if you have an item on the left and right, it auto adjusts for screen resolutions of varying sizes but still keeps the items on the ends. Source files/code will be needed along with various formats. We want it clean and professional. Will provide the rest of the details later.
