Need toilet descaling and cleaning service in Bathroom

I’m looking for a reliable handyman to perform a thorough descaling of our toilet and associated fittings. The job involves removing limescale buildup from the toilet bowl, rim, and inner workings, as well as cleaning and sanitising the area. Please bring appropriate descaling products and tools, and avoid harsh chemicals that could damage seals. I’d prefer someone who can explain the work steps briefly and complete it with care, leaving everything spotless. Flexible on dates but aiming for a morning appointment. Located in the UK, house with standard UK bathroom.
