Looking for some serious input into the best way to generate a good passive income whether it be a certain kind of site, writing a useful plugin etc. Background: * 20 years front-end development including lots of Jquery * 10 years PHP development * Passed Adwords Advanced Search exam * Sound knowledge of SEO * Good at copywriting * Have only about 8 hours a week to dedicate to it because of full-time job + family + other website I run. * Have some $$$ to invest in it * Am in Australia which rules out some things I have the skills to write any code needed and build whatever is required. I'm looking for a way to get a website/s up and running that would enable me to leave my Senior Developer role in 2 -3 years time and concentrate only on this sort of project. I'm open to ideas - such as building micro-sites for flipping, building a Wordpress plugin for sale etc. Not afraid to throw some cash at it if it seems viable and repeatable or scaleable. PM me if you don't want to discuss openly on the forum.
