Integrate new design into existing script

We are looking for a talented web developer who is able to integrate a new design (html files are available) into our existing script. Our script is a booking engine, similar to airbnb. This information would give you an estimate of the volume to be changed. We will provide all necessary html files of the new design, and ftp access to the views folder of the script (attention: full access to the root folder will NOT be provided at any time!). The script is coded based on the CodeIgniter framework. Deadline: 3-4 business days, faster if possible.
