Its hard if not impossible to hire local finished contract ones. Those who break contract msut have their reasons, which must be the employers' fault. Never their own problems.
I know hiring overseas helpers will take you long time and much effort to train. BUt gotta accept the truth. Perhaps taking one week's leave to train (if you still have).
Overseas Yan.....must interview over the phone to make sure they can understand Eng. There are millions of Yans who claim to have SIngapore experience but actually they do not speak Eng at all. I was one of the victim hiring Yans of this kind. Turned out the Yan spoke niether ENg nor CHinese, and is totally retarded.
