Recommendation of shipping & moving companies

Hi, I am currently living in NSW, Australia with my wife and we are thinking about making the move back to ON, Canada.

Being Canadians living once again in Canada, some of you probably have had your possessions shipped from where you once lived back home to Canada. Can anyone recommend a moving & shipping company that is reputable, reliable, and preferably has been used by you? If you can give me an idea of how much it cost as well, I'd appreciate it.

I will get quotes, but first want to narrow down the list to the reliable companies.

Alternatively, can you warn me of companies who I should avoid using?

Thanks
