We had the battery in our 2013 Leaf replaced with a 2015 24 kWh battery by Leo & Sons in Lawrence, MA. We are very happy with the result. They charged us $4600. We didn't have to do anything but drop off the car and pick it up later.
I wouldn't recommend a 30 kWh battery. The newer 24 kWh "lizard" batteries have much better calendar life than the 30 kWh ones, so when you're getting an old battery from a crashed car, you might well get more range from a 24 kWh.
