Go to your university careers service. See what big companies without ethics statements are trying to buy the souls of your fellow students.

We've got two big investment banks hanging around sponsoring heaps of stuff at my university - nearly every competitive sporting club is sponsored by KPMG or Deloitte (with a few by Aggregate) - and some intra-university teams have sponsorship too. Maybe there are some companies looking for name recognition amongst your student body - they'd quite fancy you standing around in a campus parking lot before rides with their company logo plastered all over your bodies.

Also talk to your alumni or development office to see if there are any good corporate connections to be made there.
