Facebook Page Design

I need a facebook fan page created that will be designed to have a similar look and feel to that of my already existing website. I need the page to be eye-catching and of a very high standard of design. This fan page will need seperate tab which is used as the landing page. When fans "like" the page I need a special coupon code which will then be revealed. This coupon code will only show when fans "like" the page. I need to be able to edit the coupon code myself in future (changing the amount in £ value or %) in a simple and straight forward way so will need clear instructions on how to do this. I would prefer bidders only who have done similaer tasks before and would like to see examples of previous job done.
