Build an Online Store

Hi In shopify before we open a online store or users can see the online shop the program give us a possibility to have like a landing page that they call "Store front password" this hapen when the online shop is under construction and what i wnat is this: Change the Store front landing page for that one that you can see in my example. I have the picture and i need like 3 links: 1) for the Facebook , 2) for the Twitter , 3) for the Pintarest and the another option to people that can see the page have a possibility to send a email to us. So please see the example Many thanks Michael London
