Google "Finding a job". There are all kinds of websites. Monster.com is a well known one.
Look up specific companies and/or big corporations in your area, go to their websites. Most companies list job opportunities or information on how to apply on their websites.
Check with temporary employment agencies in your city. Here in my city Manpower is big. My husband found employment through them.
Check local newspapers, look in the "Classified" or "Help Wanted" section.
Check your public library's main branch. They may have someone to help you with employment and similar resources. I know ours does.
