Buffet Quantity

We are having a American/Indian buffet for 150 people. We are having an American chicken dish and Indian chicken dish, Indian meatballs, pulled pork, baked mac and cheese, indian rice, 4 different salads. We are also having an hour before the dinner where we will be serving cheese, ring bologna, fruits and veggies with dips. What I need to know is how much do I need of each meat dish and the mac and cheese and rice. Thanks for your help.

We suggest the following portions per person: 5-6oz of chicken per person (both chicken dishs combined), 4-6 meatballs, 4-5oz of pulled pork, 3-4oz of mac & cheese and 3-4oz of rice.
