writing a brief description for linkedin and resume

Hi, my self Gangadhar, For two years I have been unemployed, I dedicated my time to start-up. Unfortunately, it didn't work. Right now I am looking for a job, and I need a small positive script so that I can sell my self in an interview and at the same time a brief description of experience for my LinkedIn. My field was neurology and cancer biology, I was molecular biologists. I had research experience for 5 + year in those fields. After quitting my research field I started working in my startup and spent most of the time in the research for my start-up related to fishers and prawns related. But there was molecular biology involved in it. I didn't have one experience for last two years in the molecular biology field. I need a motivational and positive script or a story with a brief summary of my LinkedIn or you can resume. Willing to provide more details if our price fixed.
