Theft attempt

I woke up this morning to find that someone had tried to nick my SV650S (1999) from my drive in the night.
They damaged the ignition barell and the top yoke to try and release the steering lock and then cut all the wires from the ignition barrell before realising that they couldn't move it because of the disc lock (best buy!).

Please could somebody give me an idea as to what it may cost to get it fixed assuming that it needs a new ignition barell and wiring and new top yoke (or is it just a yoke cover?). The workshop i use are closed this week.

Thanks
