Please view the following sites. [login to view URL] [login to view URL] [login to view URL] I would like to get a very modern looking ecommerce website to sell a wide range of replacement laptop batteries, ac adapters, hard drives etc. Site must be functional as above sites. It must be user friendly where a novice could find the products they need by easily searching for computer make and model, battery model, OEM part number etc. Site can be designed using Joomla, OScommerce etc. Google Product Search and eBay integration are mandatory requirements. I would also need the ability to do mass adwords ads based on product name, part number etc. SEO module to be included. I am fully aware that these modules can be bought. I would need them installed and I would pay for license numbers directly. I will not entertain off the shelf templates. Site must be original. Functionality will be a key factor. I am experienced with other carts so please only bid if you are capable of producing a world class website.
