It all depends on how nice you want it to look. Most notation programs don't give you much control over note placement, size of measure, page layout, line breaks, that sort of thing. Finale is pricey but is the industry standard. It will probably do anything you could ever want, including export files in a variety of graphic formats. It has a little brother called (I think) Allegro that is supposed to be pretty good and is a lot more affordable. The company is called Coda Music.
