Do you have access to flour tortillas in your area? A good (and very inexpensive) finger food is stuffed tortilla pinwheels. We made these for one of my showers.

All you do is get some cream cheese, mix it with minced black olives and chile. You don't have to use chile, however. We rolled the tortillas up and sliced them into pinwheels. Have you ever tried the veggie cream cheese at Dunkin Donuts? That would be wonderful in this.
