I live in a county of 400,000 people and we have 4 online job sites serving this area. You can find these job sites by going to any major search engine and typing the name of a city or state. For any city with a sizable population you'll find numerous links leading you into the local job market. Just because jobs are offered in a local market doesn't mean there aren't home employment opportunities. While you're at it, search local and national newspapers for jobs.
Online newspapers have numerous classifieds and links to job sites.
Using a search engine you can hunt for companies doing business in your field of interest. Use keywords which describe the type of work you're looking for. When you find a company, go to their employment or opportunities section. Submit your resume on positions for which you are qualified and can be done remotely. You won't know unless you send them your resume.
