E-Commerce website development

We need a very basic ecommerce site to sell a range of t-shirts designs. Want to be able to add new tee-shirts ourselves. in addition to the t-shirt shop pages I need an intro page with a 640x360 videoscreen. a page called "the story so far" which is text with an image, a page called "early concepts" with a series of images that you step through with arrow buttons, "licensing opportunities" which is text with one image and "contact us"
