Questions about rabbit care?

Hey i'm a 13 year old girl on the Honor roll at my ib school. I REALLY want a rabbit. | already have a finch who is 5 years old. Can you tell me what it's like to have a rabbit? What breed? How much it costs? Is it awesome? How long do they live? Sweetest breed of bunny? Work involved? And how to convince my Mom to let me have one? Thanks!!!!
