Hi maybe I can help. I was self employed before becoming a driver.
I looked into Raider Express. Two of my sons went thru their training. I decided not to go that route and went with FFE. I am happy with my decision.
Now about being self employed. I had to submit my previous years tax records showing that my employment matched what I had written and I wasn't unemployed and claiming to be self employed. Being that I was still self employed when I was going through this process I had to also send in my up to date financial records. For me it was my account receivables & payables. They didn't care about how much income it was. It was to prove that I actually was still running my business and when my projected closure date was.
I had no problem getting hired.
