Create a module/plugin for Yahoo stores

We have developed a standalone application that can be added to various platforms. We need to develop a module for Yahoo Stores platform. ******************************************************************************************************* I need developer familiar with Yahoo stores platform only. Please list projects you worked with connected with Yahoo stores ([login to view URL]). ******************************************************************************************************* About the widget: It is a service to get a discount based on social sharing. It works on any third-party website inside iFrame popup. The plugin for E-commerce or CMS websites should allow to easily integrate our service into client's website. Plugin must provide both client (JavaScript) and server (PHP, etc.) integrations. While client integration is simply including external JavaScript file, server integration may require hooking into existing E-commerce routine in order to apply discount. We will provide further details after your bid due to privacy issues. You will get technical documentation for the widget and terms of its integration. We will be paying per project.
