Getting a PR and not working officially

[DavidB]

Hi,

What is the possibility of me getting a PR if I am not officially working. I'm a freelance writer. Accepting free lance jobs from states and all over the world. I don't need an employment pass and technically it's not a business. However, my income is not fixed. My wife is a Singaporean and she earns a steady income of 2500 a month but then she has other side line job which can make reasonable amount of money. If it's possible for a husband to actually help a foreign wife to get a PR, what is the likelyhood of a husband to get a PR too if he doesn't officially work?
