Custom Woocommerce Shopping Experience Needed

We need someone who can help us develop a custom Wordpress plugin, or fork the code and heavily modify an existing plugin. This plugin manages a custom Woocommerce product selection / checkout experience for an online coffee bean seller - in this project, we want to do an overhaul of the user experience. We have the user experience completely designed, and we don't need any front-end HTML / CSS help, but we need a Wordpress Plugin and Woocommerce guru who can integrate the with the backend of Woocommerce or possibly develop our own custom plugin for the job as needed.

This is a project based contract, not a permanent hire, but if the project goes well, we may make you an offer for permanent employment (we do staff permanent positions of this type).

Thanks,
-Jesse
