Whether you've decided to make freelancing a full-time job or just want to pick up a little extra cash to supplement your existing income, the hardest part of getting started as a freelancer is knowing where to look for freelance job listings. Once you get going, however, you're likely to find that potential gigs are all around you, especially online. Here are a few places to look for freelance jobs. Some sites will be familiar to every job seeker, and some might take you by surprise. 6 Sites to Find Freelance Job Listings Online 1. Monster.com Set up a profile and become a registered user, and Monster will send you listings to geared toward your specific needs, or search their database of jobs. To find freelance jobs, include keywords like "freelance" or "part-time" in your search criteria. Monster allows users to apply directly to jobs from the site.

LinkedIn You've probably grown to think of LinkedIn's "resume on steroids" service as a way to market yourself to full-time employers, but it's also a great tool for freelancers. Once you build your profile, including a clear, professional head shot, and relevant keywords to grab potential clients' attention, you can start searching for freelance gigs by including the term "freelance" in your search terms. Better yet, use the service to network with connections at companies who might need your services, and lay the foundation for a personal introduction to the manager who hires contractors. 3. CareerBuilder CareerBuilder allows you to post up to five different resumes, which means that you can look for a variety of freelance jobs at the same time, or look for full-time work and part-time work simultaneously, while testing the waters for a potential freelance career. To search for freelance jobs, add "freelance" or "part-time" to your search criteria. (For more tips on using CareerBuilder for your freelance job search, read this review.) 4. Craigslist The granddaddy of all local sites, Craigslist is a solid choice for your hyper-local freelance job search. Go to your city's site and then look at the jobs sidebar on the right-hand side of the screen. Select your industry and search by keyword (e.g. "freelance") or go directly to the "part-time" listing at the bottom of the list. For freelance jobs of even shorter duration, the "gigs" section at the very bottom of the right-hand side of the screen offers work that lasts the duration of a project. Just beware of scams. Although it's no longer free to post jobs on Craigslist, it's still pretty cheap -- as little as $25 per job, per category, in most cities. And never give anyone your bank account number, social security number, or any other identifying personal information in order to get access to a listing or to apply for a gig.

Indeed.com Search millions of job listings, freelance and otherwise, in your area by typing in your keywords and your geographic location. You can also set up email alerts to have freelance job listings sent directly to your inbox. 6. FlexJobs FlexJobs isn't free, but it's also one of the few job search sites that's targeted solely to job seekers looking for part-time, flexible-schedule, or freelance work. The site also researches the companies that provide its listings to verify that they're legit -- and promises a money-back guarantee if you're not satisfied with your results. Although FlexJobs offers listings in Canada and overseas, you'll find the most jobs if you're looking for US-based companies.
