Realistic image of a professional painting contractor working on the interior of a large commercial building. Showcase painters in uniforms applying a clean coat of paint to high walls and ceilings. The environment should feel like a spacious modern office or warehouse in Alberta, with a focus on quality, professionalism, and attention to detail. The lighting should be bright but natural, emphasizing a fresh, inviting atmosphere. Perfect for a small to medium-sized local contractor --ar 4:3 --c 33 --s 333
