This isn't for my sorority, but actually for the Jaycees (a community service organization I belong to)

So, I volunteered to plan a charity ball for our local Humane Society. The problem is, I'm way the heck over my head. Has anyone ever planned a ball like this before? I haven't a clue as to where to start. So far I've figured out I need to make arrangements for:

• When
• Find a hall
• Music/Band
• Drinks
• Food
• Servers
• Advertising
• Decorations
• ???

How do I go about talking people into donating a hall/food/drinks/etc though? Or am I even going to find someone to donate? I want to use as much of the money as possible for the charity of course, so I really want to get as much by donation as possible, but aaargh!!! I've never done this before! Help!
