I would google all the major insurance companies you know....go to their websites and then look for a tab that says something like "career opportunities" or "employment" or something like that. Usually you can search your area and see what jobs are out there. You can usually upload your resume right from their website. Companies are making it alot easier to apply for jobs with the web.
I work for an insurance company doing Utilization Review and Case Management and I found this job in the local newspaper. We do have nurses who work from home, but I do not. I chose an alternative work schedule instead. In our company if you work from home, you have to work Mon-Fri. I chose a schedule of Mon-thurs 8:30 to 6pm with every other Friday off.
