Need quick wall patching to fix a small hole

I have a small hole in my living room wall from a recently moved-in item. I’m looking for a reliable handyperson to patch and sand, then repaint to match the surrounding wall. The area is about a 5cm circle. Preference is for someone with experience matching light grey paint. I can supply spackle, sandpaper, and paint if needed, but I’d appreciate guidance on the best materials. Please mention ETA and any prep work you’d recommend.
