Self employed but want to enter in express entry

[Shikha jaggi]

I am self employed and having experience of 5 years in automobile spares retail. Business is registered since last one year but operational since last 5 years. I do have purchase bills of last 5 years. My consultant is saying he will file my case into express entry with my experience. My work duties Is kind of similar with some NOC. I want to ask whether I would be eligible through express entry or i should try business class migration and what are the chances in case I apply under business migration.
