Have you considered using a framework like Twitter Bootstrap or something of that nature? It sounds to me like that's the way to go to launch quickly. I expect what you'll find is that even though the designer may have made an awesome design the requirments change and you'll need to 'redesign' sooner rather than later. So, you'll be stuck in the same place again. Twitter Bootstrap lets you get around this problem and provides you'll be able to maintain it long term.
