I've worked full-time as a consultant since 2007 and make a little over low six figures after taxes and paying contractors. We (http://www.goodproduce.net) do a lot of basic services like content development, web design (mainly WP), social media management, hosting, deck creation, and general "digital" consulting for high net-worth individuals (primarily athletes and their brand partners.
In the early days, I worked to stay visible through conducting interviews for my company blog - that got us on the map in the sports community. It also helps that we never say no to a request...ever.
