eCommerce webpage design

Hi everyone, Please note I do not require development/coding of the website, I am ONLY looking for page layout design. I am building a website for CS-Cart, I have designed the homepage already, now I need page concepts for the product grid, product table, product description, and category pages. Also one for standard html page. The successful candidate will be able to demonstrate a selection of at least 5 ECOMMERCE website designs. You will need to have the ability to justify the design, and consider usability, online retail trends etc. I am looking for an aesthetically pleasing and easy to use design for these pages, based from the PSD homepage file. Thanks
