Design and Implement dynamic and beautiful UI for an online booking platform

Dear Freelancers, We require a User Interface expert to design and implement a graphical user interface for the business dashboard of an online booking platform. The UI needs to direct the user through the various tasks they need to perform after they have registered. The other key component of the UI is a booking calendar. We use the Codeigniter framework (PHP). For those who we view as potential candidates, we will provide the details of an existing website which we would like to model our UI against and also our existing UI. We would like to achieve a 10 day turnaround on this piece of work.
