That's one useless designer.. if the designer does can't produce their own fucking design. That's where we get photoshop monkeys.
30 mb PSD vs someone who can code their design. Your pick.

I've did both: having a design than translation to HTML and people that could do both
There's an advantage to someone that will focus only on the design and another that will focus on only translating that to HTML/CSS/JS namely, that someone that can do both very well is rare
But of course, if they can do the design and a basic html/css of it usually can move the project faster. You will not have the greatest design or greatest html/css but it will usually arrive at a good solution
