I would just go and buy a monologue book. The best way to find monologues is to actually read the plays straight through, b/c monologue books are overdone, but it sounds like you're in a bind for time. I like monologues that have an arc, as opposed to staying in one place for the whole piece, and that's usually what makes the monologue more interesting. I did a monologue about a driver in rush hour traffic, and while it was funny, it was just this guy bitching about rush hour, and it didn't go anywhere. I like mine to have a decision made or a change by the end of the piece. Best of luck!
