They have ones that are already made, about $20 for 8-12 people. They have bigger ones too, which of course will cost more. Also, it depends on what kind of fruit (if any) that you want in it. Special fruits, like Mango, will cost just a few dollars more.
20$ Depends on the size, best thing to do is call and find out.
