While I was unemployed, I did conversions of sites to WordPress themes. I was fast enough at it that I could devote most of my time to other endeavors. Since I didn't do content creation for my domain, SEO was out of the question, so all my traffic came through AdWords. With well targeted keywords, my CPA was ~$20, and the average client took 5-10 hours of work, since they'd often want content migrations, too. It took a week until I made my first dollar, and for the few months I did it, I brought in ~$700 a week, while never taking up more 20-25 hours a week, while also doing more committed, serious freelance jobs. I dropped it, though, when I got a full time job, though I'd probably pick it up again if I found easy to work with subcontractors.
