Need help installing a light switch in living room

Hi there, I’m looking for a skilled tradesperson to install a new light switch in my living room. The wall is plaster with standard electrical box, and I have a single-pole switch ready to go. I’d prefer a tidy finish, to ensure the switch is properly wired and meets safety standards. If you can also provide a quick safety check of the nearby outlet and light fixture, that would be great. Local Ireland regulations and receipts preferred. Please let me know your availability and estimated time to complete.
