Create a plugin to add a very simple feature to WooCommerce.

We need professionals develops in PHP who can create plugins, we also need a designer to designs some simple images with the plugin. What you required to do it the following things: 1- Build a plugin and test it and make sure it compatible with woocommerce v.1 and v.2 2- Design multiple images. 3- Write a documentation about the plugin and who it works. The plugin details will be sent after bidding. (BTW before you price, the plugin is very easy I wrote some of it, and I believe it won't be hard!) Thanks!
