Berkely Big Game 40lb is about the cheapest running line and is pretty good. Split a spool with some buddies and you will only be out a couple bucks. Just be sure to stretch it in the morning before you start fishing.
Then you still have almost your whole budget to go to a local shop and pick up a head, sinktip, and some local knowledge.
