I dropped my iPhone 5, can I get it repaired and how much will that cost?

It slipped out of my hand just as I was taking the case off! Half of the screen works. There's lines going up and down the screen (not cracks). The right side is unresponsive to touch but the left side is fine. Can this be fixed? If so, how much will it cost? I want to know if it's cheaper to get a less expensive phone or to get this phone fixed. My lock button doesn't work so I can't turn the phone off.

Leave the case on. It will cost 200
