Over the last two years, I've taken over a web application development group.  My focus for the first two years was building teams, get technology updated and in-place, and fixing my customers pain points so we can begin moving forward.  We recently starting building new applications in MVC, and I'm finding that my junior and mid-level developers are struggling to build the interfaces, since there's no more drag and drop.  Given that I don't have a deep pool of true html talent, I'm trying to determine if I need UI designers or Web designers to create the interfaces for the applications. I also don't want the designer to be bored to tears either, but that's the job.  Is this something that's typical for this situation, or am I better off bringing the developers up to speed with HTML/CSS training.
