Slider images - repost

I need a series of 7 images for a slider on a website, all of which need to be 960 x 400. Since I will be adding text these images need to have white backgrounds and sufficient blank space. Although I have a concept in mind for every image, I don't have any pictures from which to work with, which means that I will need someone who will use some creativity when necessary. Though I obviously prefer to keep costs down, If you feel a paid stock photo (within a reasonable price range) is necessary I will purchase it and send it to you to work on. The style I am aiming for is clean, simple, and sleek (eg. Apple's website). Happy bidding.
