Create a catchy graphic for startup

Need to create a catchy graphic design which will be used as facebook landing pages. The website, which is yet to launch is [login to view URL] As the name suggest it will let users to about the latest discounts and offers. It has to attract youths who spend big bucks on shopping. Design should be catchy, should connect to the audience. Later on I will also be needing logo, business card etc for this website. The banner will attract users to subscribe to newsletter as well as like our page on facebook. Its a pre launch campaign. Looking for low budget designers only.
