Website Design For an Online Store

I'm looking for someone to build and design an eCommerce web-store for our company. The shopping cart software should be from one of the more popular or open-source eCommerce shopping cart solutions available today. I am familiar with OpenCart, Prestshop, Magento systems, but I'm open to other suggestions like Zen Cart, OS-commerce or others. I'm looking for a clean website design with customer friendly layout. Needs to look high quality, professional, and modern web style. I'm open to your suggestions and creative input. I have not decided on color scheme or branding color yet, but web-store background will be dark and possibly contain other textures. I do request to receive a copy of the original source templates and graphics so that I could edit my website content, colors, or style formats as needed. I will need to see examples of your past work on ecommerce shopping cart software before accepting your bid. Please feel free to contact me with your example portfolio or ideas. I will reply with my ideas and thoughts and we will start the coloration process.
