500 visitors a day on that keyword alone is possible if your in the top 5, probably 300 if your in the top 10. Of course if you rank good for 1 big keyword you almost always rank good for many smaller keywords.
Here try this tool. http://inventory.overture.com/d/searchinventory/suggestion/ it will give you an exact figure how many people type your target keywords. So more or less if youre page is on the first page in a search engine you will get almost all that traffic.
