Migrate an existing website to a mobile responsive design

We host a number of websites and are in the process of migrating them from their existing design to a mobile responsive design. This project involves migrating a single site to a mobile responsive design. Here is an example of a mobile responsive site (source site): [login to view URL] Here is a non-mobile responsive site (target site): [login to view URL] We will provide you a zip of the CSS for the mobile responsive site (from source site), and access to our Development environment where you will access a Content Management System that stores the templates that defines the layout of these sites. We will also provide you some further instructions on how to interact with the CSS. There are 5 separate areas to update that comprise the entire application, and each area has approximately 25 HTML fragments that will require updating (each fragment defines a specific section of a page - for example a header, table row header, table row body etc...). Your job will be to update the HTML templates and CSS to update the target site to mobile responsive design, maintaining the overall brand/ style of the target site. Specific content of the existing target site (for example form fields) must remain the same as the existing target site. ie, you are just updating the look of the site to mobile responsive, not impacting the existing content, forms fields or validation. Depending on the price for the work and resulting quality, we have a number of these sites to be migrated and there may be an opportunity for further work.
