legitimate medical billing from home

Does anyone knows of a legitimate billing job online and that's free of charge?? Any comments greatly appreciated. I have been doing billing for six years but don't have any certification.

There Are No Legitimate Home Based Medical Billing Jobs (meaning that you are hired by a billing company, practice, hospital, insurance carrier, etc. to perform the task of processing the overflow of claims that the company has acquired). Medical transcription on the other hand is the type of home based business where you can contract out with companies both regionally and locally to transcribe their workload as a home based job. Instead of making this post long visit the following website and see a full breakdown of why medical billing jobs from home don’t exist:
