Possible reception food

This weekend I spent a lot of time thinking about wedding related things. I spent a lot of time thinking about food. Since we are having 2 receptions, one at the University and one at our house I have to budget and plan for 2 receptions. This is what I have came up with so far.

University Reception
-fruit and dip (maybe not dip) $125-with dip
-cheese ball and crackers $ 95
-vegtables and dip $ 75
-meatballs $ 65
-chicken salad croissants $180 (*I would love to have 50 chick salad and 50 pimento cheese.)
-tea
-lemonade
-plates, napkins, cleanup
I figure that having a 2pm reception people won't expect to be fed a complete lunch. To me this seems like adequate food, and does not include the wedding cake. I may do another meat-chicken tenders.
Budget would be around $500-600 for this reception for 100 people.
*Now looking at the food and the cost for the reception I'm wondering if we could do the food ourselves.

Backyard Reception
I don't have a list of foods that I would serve for this reception. I would do most of the food myself and probably order the meat. This reception would be for about 30-40 people and this would be an informal dinner reception. I would like this food to reflect what foods we like and be easy to make and clean up.
I think that if we could stay around $400 for this reception that would be fantastic.
Looks like our ideal food budget will be around $1000.00.
