Can i get my iPhone fixed? How much would it cost?

I have an iPhone 5c now. But before this one I had the iPhone 4. But me and my bro were playing and it hit the wall and fell on the floor. (Don't even ask) but I've been bored and just started chipping of pieces and you can't go on it. You can turn it on but there'll be a white screen. Can it be fixed? If so how much will the price be?

I would just upgrade if your contract is up, better off spending your money that way instead, or just get a new 5C on contract free.
