That said... the lower price that people get from me does not include the assurances that accompany an insured professional. These people take a risk everytime they let me into their home, because if I trip down the stairs and break my back, it is they homeowners insurance that is on the line. If I stupidly step onto a granite countertop overhange and snap it, I have not liability insurance to sue.
Paint supplies cost anywhere from $10 to $100 or more depending on what you need. Painters will typically provide most of the supplies for a project, but sometimes they will allow you to pay for solely labor if you provide all the materials yourself. You might decide to do a DIY paint job down the road. In which case having these supplies on-hand will save you time and money.
"Rafael was very professional, detail-oriented, pleasant to communicate with (responds promptly, returns calls, confirms appointments) and always showed up on time. He painted my daughter's room beautifully and for a reasonable price (offered pricing with and without paint). His work was precise and without mess. I will definitely hire him again for more painting projects."
