If you are specifically looking for a college student, You should try at college fests or such events where web design competitions are held. Just participate in some of these (even if you are bad at design, just participate to meet people and also try your luck. You might be good at design yourself) and you'll see some guys recurring at many competitions. Find out if they are winning atleast a few times in those competitions.

That's just one way of doing it.

Why not a HN job post about your requirement? :P
