Shopify Product and Tracking Module/Plugin/Extension

We would like to commission a job to build a plugin/module/extension for Shopify that has 2 purposes: 1. Extract all products or a subset of products via the CMS admin menus with the output either as XML and/or CSV. We require that each output has the following column names: Product name, description, brand, product ID/SKU, deeplink, image URL, price, category, in stock. We will provide further documentation relating to other required fields. 2. We require a separate admin menu item that allows us to customise a code snippet that is required to be placed on the order confirmation/thank you page. Please see code in the attached documentation for more information on this. This is very similar to setting up an advanced Google Analytics tag.
