If you do decide to make it a full-time business, the sky’s the limit. The house flipper/contractor that I worked for billed clients $35 per hour for painting, and paid his best painters perhaps half of that, so there is room for some profit there. Consider the case of Matt Shoup, who started with $100 and went door-to-door, asking neighbors if they needed some painting done, then built a painting business that earns $2.5 million per year!
This painter Scot never came and finished the job. Texted me at 6:30 in the morning saying that he isn't able to do the job I gave him. I would not recommend this painter to anyone. I will make sure everyone I know won't use this guy. He is the worse business owner I have ever met. I don't know how he is in business. Be very careful of this guy Scot. Don't trust him and don't pay him for anything for any work.
