The best way to find jobs online is by building a client base and working freelance or by starting at a company that allows for telecommuting. If you're in a creative field you can showcase your portfolio on sites like iFreelance. Or if you are trained at something such as bookkeeping you can find freelance work on sites especially for freelancers (Elance.com is a good one). Stay away from "work-at-home" jobs posted on job boards. Most, if not all, are scams.
