WordPress WooCommerce - Complete Custom Plugin

I have updated a custom plugin for WordPress 4.2.2 and WooCommerce 2.3.11, however I would like to add a feature to this plugin to work with variable products. In it's current state, it only works with simple products. The current plugin creates a tab on product pages to display information, I would like this information to change when a user chooses different variable products. The plugin uses PHP, AJAX, and jQuery to gather and display the information on the frontend. A strong knowledge in these languages are expected. I'll happily provide many more details to the winning bidder about the scope of the plugin and it's functionality. The winning bidder will have access to a gitlab repository where the project is hosted, so a basic knowledge of git is expected. I can happily setup a website, with test products to test the plugin in a "live" environment, but the winning bidder is expected to have a local setup for development on their machine. In order to properly test this plugin, the winning bidder will have to have a working WordPress install, with WooCommerce installed, along with dummy variable products where the price changes depending on at least one attribute (think of a t-shirt with small and large attributes, where the small is $8 and the large is $10). This is the type of variable product you will be working with. **REMEMBER** The plugin itself is written. All it needs is a feature added. Timeframe: 7 days. PLEASE CHECK REQUIREMENTS BEFORE BIDDING! Here is what is required: * Your availability is required, I'd want to establish communication through some messenger, preferably Skype. If you're able to communicate via phone, all the better. * Please be fluent in English. Thank you for taking the time to read my project. I look forward to working with you!
