baby shower price ranges?

Steph
I was looking at baby shower catering services (I know, I'm way ahead) and it's like almost $1500! Just for the food service! We spent about $3500 for my sisters shower, but I can't ask my family to spend that again! What does everyone think a healthy range for their showers is?
FYI- I wanted to do a co-ed picnic at a park by the beach. The park is cheap but we have like 100 people. We both have big families.
