Think pounds of meat instead of number of pieces. For an entree dinner service, plan on 1/2 lb per person plus a little extra; 40 - 45 lbs. For a lighter service like lunch or brunch, you should plan on 1/4 lb per person plus a little extra; 20 - 25 lbs.

That depends on your calorie needs. For people who need only 2,000 calories, it should be no more than 65 grams.
If you figure roughly 2 sandwiches per person... And each sandwich is 1/4 the size of a regular sandwich... That works out to 25 whole sandwiches cut into quarters. So the real question becomes how much roast beef do you need to make 25 sandwiches? I figure 1/10 of a pound of roast beef per sandwich should be adequate. So that means you'll need about 2.5 pounds. A full sandwich before cutting would be 4/10 of a pound of roast beef which is almost a half pound, so I think 1/10 of a pound would work nicely. And to be on the safe side, I'd make 60-65 mini sandwiches just to be sure.
