Office Paper Shredder - Not Working (Bordesley, Redditch B97)

Fellows office paper shredder, Model LX50.
This is not working; needs someone that thinks they can fix it up.
Possibly a new motor as there was a flash and a bang and now nothing happens. The power light comes on so its not the fuse.
If you want it at all, please make a request by Wednesday 29th July, other wise its up the tip that evening!

Thanks for looking.
