Convert a template to a responsive website with SCSS (+ optional implementation into a PHP framework)

We have complete designs in PSD which need to be converted to HTML/SCSS and the site should be made responsive. We already have most pages converted to HTML/SCSS, but they are not responsive yet. It's up to you to decide whether you can reuse the existing code. Experience with Git, [login to view URL], PHP, Yii2 is a plus. After converting the template you can choose whether you also want to implement the result into our PHP framework (using Yii 2). After this project we will definitely have more project opportunities, so this could be the start of a long term co-operation.
