I have plenty of experience with dealing with Newspaper campaigns in terms of following media schedules, dealing with production/artwork dept's in local newspapers etc., but unfortunately not with running a full campaign.

A good place to put up print ads about techy stuff is billboards in colleges, just walk in with some bluetack and stick one or two up - Students respond very well to Print ads on "their" billboards.
