Big Cartel alike development

Hello, PLEASE READ CAREFULLY BEFORE YOU PLACE A BID. YOU MUST HAVE A CLEAR UNDERSTANDING OF HOW BIG CARTEL FUNCTION BOTH TECHNICALLY AND AESTHETICALLY! We urgently require developers who can develop a stand alone eCommerce CMS solution similar to Big Cartel/Shopify. However, we do not require sign up plans with user registrations. It has to be a stand alone script installation (like Open Cart or osCommerce) that can be easily installed and then skinned/themed/templated. Open Cart & osCommerce are techincal & complex shopping carts, therefore, please have a look at BigCartel and Shopify back-end instead to understand what we are looking for: + ease of use (for example how easy is to add new products) + shipping costs + additional product options + promo codes + images + quick paypal checkout (with no registration) Put simply, we are looking for something shiny and user friendly - simplicity and style over complex functionality. Users must have the same experience as they would with Big Cartel or Shopify, hosted on their own server and with no contracts/sign-up fees. It has to be coded for users with little or no technical skills, who require an easy and quick way to sell products online. We will provide you with style graphics and full feature & field list to be integrated. YOU MUST PROVIDE US Estimated cost, Time scale for completion Programming languages you will be using to achieve the above. Solid portfolio of your work done in the past.
