create and upload an online shop - repost

I need a simple online shop developed to be hosted on my dreamhost space. This is to sell mail order hair products. Initially there will be three products but I would like the ability to add more myself. I have a logo designed with colors chosen for the site (attached). Apart from product pages, I would like five information pages worked in the navigation structure. All pages will have images and text. I usually use Drupal to make my websites because I can maintain it myself, but I am open to suggestions from a designer. I don't want a fancy flash landing page. You can use Flash elements but I would like to be able to amend the navigation, text and images myself. You can use any open sourced software that can be hosted on dreamhost, and that I can use myself to maintain the page. I use PayPal to accept payments. I would like you to: 1. Design the website with mock information and images 2. Insert my text and images 3. Upload the site to my dreamhost space 4. Make navigation and shopping cart functional 5. Test 6. If needed, explain to me how to maintain the site. If the software will require updates, could you also quote on performing that maintenance for 1 year.
