Why dont you just call an escort agency. It is my understanding that there are always Uni girls willing to earn some extra cash.
Just get one 'delivered' and if you like her she is sure to give you her cell number and take it from there. Be prepared though for short sex sessions and long expensive shopping trips!
I appreciate that this removes the 'fun of the chase' out the relationship but if you are just looking to shag a Uni girl this is the easy way to go.
I had a couple few years ago. The sex was OK but you are better with proper working girls for a real good time.
