Custom Wordpress/WooCommerce plugin

We are currently working on a Wordpress/WooCommerce plugin for a client we are under NDA with so I'll explain what the plugin needs to do in general terms and give a full breakdown to qualified candidates who sign the NDA. The ideal freelancer is a bonafide PHP developer who has built or contributed to Wordpress plugins. Also-- this plugin is based on WooCommerce so you'd need to have an advanced understanding of Wordpress and WooCommerce's actions, filters and best practices. Our client needs to process orders from initial reception to completion. This order process is different in that the frontend "shop" aspect of WooCommerce will be disregarded. There's no frontend customer at this time. We'll be using WP & WC because they already handle things like authentication, roles, orders, etc. but don't think of it as a traditional WooCommerce setup. This plugin will essentially convert the front-end of the site to a dashboard for Customer Service agents to track and action WooCommerce orders. We're attaching some additional fields and taxonomies to Orders to fit our client's one product that is ordered and tracked. This product will be ordered and the order fields will be updated along the way during their order completion process which is very manual at this time. There are several vendors that need to receive information about open orders and take action on them so we'll need to create custom order statuses and be able to send emails and do other WC-based actions depending on the order status. You'll also need to be familiar with outputting these orders with their custom fields to CSV and possibly to PDF. We don't mind if you hack/extend any open source products and we might have found a plugin to do most of the work for us for the PDF attaching and emailing that you might just have to customize. This project is for developers who want to start YESTERDAY, and are available now. You'll work with a project manager and mostly be concerned with the difficult WP/WC integrations and some custom PHP functions and other team members will be working on the frontend. We've already got a headstart on the project in a GIT repo so you'll need to know how to use GIT to contribute your code to it and how to use branches for individual feature sets since there will be multiple collaborators-- we've tried to separate the views and logic so far. You should have a solid knowledge of standards-compliant HTML markup and basic JS functionality as it might relate to Wordpress Ajax Admin calls or things of that nature on the frontend but the rest of the frontend work will be based on your plugins' output and markup. There are no files or examples we can show you without an NDA but if you've built serious WooCommerce or Wordpress plugins and have time now, we can sign the NDA with you and send you over some materials.
