Full rebuild of ZD30 engine

Hi, hoping someone can put me in the right direction please.
We have a 2008 Nissan patrol ZD30. I have been told it has a cracked cylinder head and maybe other damage. A good friend who knows engines has said that best option would be for a full rebuild because we want to keep the car. It had done 290K.

Can anyone please tell me who rebuilds ZD30 engines in Queensland, preferably in Brisbane, Sunshine Coast or Fraser coast and any ideas on cost. I understand it's not going to be cheap.

Any feedback will be really appreciated.

cheers
