There's also a gap I'm (and I'm sure most designers, unless they do everything by hand) sitting in, which is I know enough about web design to leverage UI frameworks like Bootstrap/Foundation to make nice designs. I think people forget that bootstrap and zurb are easily customizable. It starts as a prototype in vanilla zurb (usually), then gets themed into something pretty.
