Not sure where you are located, but most big cities have regular tech networking events, seminars, skillshare classes, etc. The VAST majority of rewarding, quality work I have done freelancing was for real-life people (businesses, many startups, etc) that I met at network events. Get a decent personal business card and make sure you tell people what you are capable of doing, and that you are available for work when you meet them. You will be surprised how many opportunities come out of the woodwork.
