Starting a small ISP

I am a student and I have to do a project for my CIS 288 systems project class. I have to design a small ISP from scratch. I have been to several big book stores and I can not find any anyformation on where to start. I have visited a small ISP and they have only 300 users that is what i had in mind. Information systems is what I am trying to get my degree in bur really we have only taken one networking class. I would appreciate any ideas on a starting point.
