I would say you come alone if that's an option. Once you get a feel of the place and what it has to offer you, then you can bring your family.
Bring as many things as you can from there. Things here are very very expensive. When compared to your home country, it's going to shock you. Get your entire kitchen if possible and also towels, curtains and bed spreads and such other things. Basically get whatever you can from there. Apart from your winter jacket and winter boots, nothing else is very different from what you would get there. So you may leave these 2 things to buy here, and get everything else from there. This is my advice.
Trust this helps.
