CSS work on Wordpress Theme - 10 HOURS TO COMPLETE

I need two things. 1. I need the navigation to be split into two lines with a clear space between them. I have attached an image of how it currently is and where there needs to be a clear space. 2. I need "contact" to show up in the top navigation bar. 3. I need the front page tiles to be resized to match the attached mockup. They must all stay responsive. Must be done in the next 10 hours!
