Repair and repaint a damaged section of wall – $400 all-inclusive

Looking for someone to repair and repaint the blue section of wall shown in the photo. The wall was accidentally knocked, causing paint to chip off and leaving scratches. The job includes preparing the surface, filling where needed, sanding and repainting for a smooth, even finish. I already have the matching paint. You will need to bring your own tools, equipment and any other materials required.
