Banners for Silverinvest.no

I want 1 banner sized 1000 x 300 pixels, and 6 banners sized 300 x 133. You can see here how they will be placed in our webstore: [login to view URL] We will use the banners as templates to promote different products, and I will need the photoshop-files. You can see the banners we use today, and the amount of text we have on each. [login to view URL] We are selling silver coins, and the style should be a bit serious, but not boring. It would be good if the banners somehow work together, so it looks like "a whole" not 7 different objects. If you make it this way, have 6 layers/groups that we can turn on/off, after which one of the six small banners we make. If you can show what you want to make, what kind of style you suggest, thats good. I probably will not give you the job if I dont know what you will make.. Let me know if something is not clear..
