cell phone parts store - open to bidding

I need to build an online store, specifically for the wholesale of Iphone, ipod, ipad, and Samsung galaxy parts. There are many websites that currently sell cellphone parts, both retail and wholesale. I need a website that has a sleek, clutter free store. I am looking to be different from my competition, not just by lower prices, but also by having an extremely simple and user friendly online store. I like how simple [login to view URL] lets new & existing customers go on their website and add items and place orders seamlessly. It should only take 2 clicks for the customer to have his/her order placed. Should have payment integration as well. I don't want a traditional layout, with endless tabs for all the product. It should be simple. And easy to maneuver through. To get an idea of the products i will be selling, you can check out [login to view URL] I will be selling most of those same parts, at lower prices (i will only be selling the iphone,ipad,ipod, and samsung galaxy, and note parts initially. later i will add more parts). I should be easily able to go in to change prices, add or delete products at any time. I also need help driving customers to my site. It is extremely important for me to have a sleek, yet very simple online store. The online store is wholesale customers only, with a minimum order of $500US. All orders have free shipping. I am from Houston, Texas USA, and most of my customers will be through out the United States
