Need help installing wall mirror securely in living room

I’m looking for a reliable handyman to mount a wall mirror in my living room. The mirror is about 60x90 cm and will require drilling into drywall and possibly finding a stud for extra support. I can provide the mounting hardware, but I’d appreciate guidance on the best hanging method and safety precautions. You should have a drill, level, stud finder, and appropriate wall anchors. Please confirm you can handle a secure installation and can work on a weekend if needed. Location is in the UK, and I’d prefer a tidy finish with the mirror perfectly level.
