Start with your own network. Past colleagues, friends, friends of friends, etc. See who needs web work done. Then add on industry events. Go to local meetups and talk shop. This won't necessarily find you clients directly, but it will help you meet other freelancers who can refer you work when it's not up their alley or when they're too busy. Once you start getting some clients, use them for additional work too. Ask them to recommend you if you've done a stellar job. It's generally a snowball process. You start small and then start to gain momentum once you start doing some solid, quality work with clients who like you. Word of mouth is insanely powerful in this business.
