i was wondering if anyone could help me get on the right

Hello i was wondering if anyone could help me get on the right start to creating a website I am wanting. I found a website example that i really like http://fitmiss.com/
I really want to create a site that has a menu and logo area like this. I dont want the white at the top of the screen, just the grey and pink menu parts. I think it looks clean!
Is there a theme I should start with that would help or maybe some tips, anything would be a huge help, thank you!
