Need help mounting a TV on wall securely and neatly

I'm looking for someone to mount a flat-screen TV on the living room wall. The wall is plaster with stud framing behind it, and I want the bracket to be properly anchored to a stud if possible. I prefer a clean, low-profile setup with tidy cable management and no damage to walls. The TV is 55 inches, and I already have a compatible wall mount. Please bring all necessary tools, level, and ensure the mount can support the weight. If there are any safety considerations or height recommendations, I’d love your input. I’m flexible on the timing but would like it completed same day if feasible.
