YES, I agree. The mentor provided "a free trial": to determine whether he could help me. and then to show how he would do so. He also required me to accept a 2 hour shared screen session which was also no charge. Next he explained how he was to be paid and a written money back guarantee. All this was done with no credit card required. So, that sure eliminates the scammers. He did require evidence of my working on what he taught , using homework assignments, which were graded before the next scheduled online session. I actually was able to pay out of profits and yes it was really fortunate that I found him.
