Apply for jobs on oscar plus, ask around place to place, look for adverts that certain departments are hiring, talk to profs, ... ???
Titles does hiring for preparing for the September rush, places like hospitality services (food) are always hiring, pretty sure The Sil is always looking for writers and submissions, AVTek (tech) hires in the summer/november and year-round, most of the coordinator positions for the various services are hired over the summer and sometimes winter, and... that's all I can think of.
