I need someone who knows his way around Photoshop, CSS, and visual design, and I don't have a couple years to drop everything and go learn that.

CSS isn't rocket science either. It's a variant of html (sort of) where you choose stuff like font and background color (style, I guess) in one master document that all the other web pages refer to. It's like the Slide Master in powerpoint. It has slightly different punctuation than html, but it's not that special. It's just an easier system, and it's probably overhyped by design bloggers.
Visual design: there's all kinds of "7 mistakes begginers make" type articles in hacker news. Some are better than others. Just use common sense, good taste, effort, and knowledge.
That should get you acquainted with all three problem areas. In fact, after a few weeks one can design clones of homepages of Yahoo, Google, YC, delicious, facebook, and so on. Of course, I don't know what level of mastery you're talking about, and there's definitely a lot of fancy things you can do with photoshop that take a lot of knowledge, but the kind of design chops one needs to do a startup aren't that hard to get.
I'm reading the Head First book on html and CSS. I didn't know anything before I started. It isn't hard to pick up. http://www.oreilly.com/catalog/hfhtmlcss/index.html
Put whatever crappy design you can make on it, and then take it to some of the big name designers, and see how things go? Even if they do it, a few bucks to them and I'm sure they'll post about it on their blog... they get thousands of readers.
However, if the functionality of your app will be greatly expanded then it may also require changes to your CSS. Alternatively, you can skip a large amount of design. People don't access your website to see its innovative style. They access your website to get useful information.
