Why are you doing this? As others have echoed, you’re not a CEO. The thing the consultant saw in you was a very loyal, hardworking guy, desperate to prove himself. He took advantage of that.
Why would you be spending anything to help this business, in which you have no stake, grow? It legitimately sounds like they aren’t aware you exist. If someone completely different was there next time they stopped by, would they notice? Why are you helping these people?
I had OSHA show up on one of our job sites basically because they were driving by one time. Only thing they got us on was the wrong colored extension ladder. Other than that, never seen them.
