Hello, we are from Onigi[dot]com need someone to convert purchased Themeforest templates into our eCommerce platform template engine.
We use Liquid templating engine. It's exactly the same with what Shopify is using, apart from different variables and liquid layouts.
We can provide you with the full templates design already in HTML/CSS and PSDs and documentation on how to convert it into our templating engine. Or you can even go to [url removed, login to view] and learn their system, then you can just implement it on our system using our own variables.
This is a one-time project for now, when you have good converted templates, you can later sell it on our themes marketplace for our users.
