Where can I find a replacement LCD screen for my EOS 7D?

My 12 year old daughter knocked my camera off from a desk and it landed rear side down on something sharp which has totally wrecked the rear LCD screen.

I walked into a camera shop earlier and they said it would have to be sent away to Canon to be fixed which would mean parting with a large sum of money.

I have tried searching for replacement LCD screens but either I'm being a bit dim or they are pretty hard to come by.

Can someone point me in the right direction as to where I can find a proper replacement screen - thanks.
