I am catering my nephews wedding, they have invited 225 ppl 25 of which are children. I have selected chicken and beef fajitas, stuffed shrimp,and sausage. Sides will be beans,spanish rice. There will be a salad bar,fruit bar and tortilas. The couple has choosen chips and salsa for appettizers. My question is how many ounces would I calculate for each item per person? The dinner will be from 6-7:30pm. I have calculated abt 2-4 ounces per item - is that right? If not can you please advise me.

beans, 8 pounds dry per 100
spanish rice, 8 pounds dry per 100
