CUSTOM 1 page SQUEEZE PAGE on WORDPRESS - no scrolling

See attachment below for reference. We need a custom word press template for our squeeze page. Everything must be visible without scrolling. After the user signs in, we want it to redirect them to Wordpress plugin called Contest Burner. Here, the the same information they typed in before (name & email) will already be filled in the boxes, they just need to click enter to officially enter our contest. The reason we must do it this way is because the Contest Burner sign up form is too large to fit on this page, it's too ugly, and it is not customize-able. The tabs on the top right are links that lead to information pages, and a gallery. Not shown in this image is our social media icons, which will also need to be active links - facebook, twitter, instagram, and youtube.
