Well for me, I had friends with companies who needed some help. I ended up taking over a project that was on a stupidly short timeline, and the other guy had flaked out. I did a good job, and that led to introductions to a much bigger company who provided work for several years. Basically networking. This was in like 2007, so I don't really know what the landscape is like now, or how you find jobs. I would assume it's easier if anything, because it's just a larger space with more resources, but what do I know. I stopped being a sole proprietor in 2010, and joined a consulting company for the next 10 years, and am now elsewhere, as a salaryman. If I were starting today, I'd probably look at job postings anywhere (LinkedIn, Indeed, whatever) and even if the job posting was for a salaried position, I would contact them and say "I am a freelancer, and if you can't find somebody qualified, or if it doesn't make sense for you to hire someone on a permanent basis, please consider me." /shrug
