I don't know anything about WUSTL, but I had similar issues with my local University, which has a great CS department, but we found the normal channels too complex. We contacted the University ACM chapter and threw them a party -- pizza, wings, XBox, music, etc. Told them to bring resumes and had enough of our engineers around to answer questions. It was fun and we got our hire.
