I don't mind you asking! I wish I could be of more help. I've had the same "freelance boss" for the past 6 years. I've worked on a dozen different projects with him; some were his own ideas, but most were for his various clients. I met him through a friend who also worked freelance at the time. This was back when iOS development was in huge demand, everyone thought they had the killer app idea.

He was more than happy to hire a 17-year-old programmer for about $25/hr. I now charge about $120/hr.

I have no clue how he gets most of his clients. I suppose I'm in a privileged position.

This came up on HN a week ago, might be helpful :) https://news.ycombinator.com/item?id=8908279
