Need to patch a hole in wall with plaster and paint

Hi there, I have a small hole in the living room wall from a previous shelf mount. It needs patching, sanding, and a light paint touch-up to match the surrounding wall. I’m looking for someone precise and tidy who can match the texture and color. The area is about the size of a hand. Ideally, you can bring patching plaster, sandpaper, and a little paint, or provide guidance on what’s needed. I’d prefer a weekend appointment if possible. Please let me know your estimated time and any prep steps I should do beforehand.
