If this is inappropriate for the forum, I apologise and delete if need be.

I am a hobbyist programmer for Mac OS (12y) & iOS(6y) with NO commercial experience whatsoever. 
I am asking for advice on how to get/do freelance work (where/how to advertise, where to look, etc). I am aware for job websites advertising contract work. 
I programming languages C/C++, objective-C, swift, xojo (mac version of visual basic), html (basic), javascript (basic). 

I live in Christchurch. 

Thanks for any help
