Need a plumber to replace a bath drain in my Irish home

I’m looking for a reliable handyperson to replace a bath drain in my bathroom. The current drain is a bit slow and sometimes leaks when the plug is inserted. I’d like someone who can supply or advise on a suitable replacement, check the trap, and ensure there are no leaks after installation. It’s a standard bathroom setup with accessible pipes under the tub. Please include any recommendations for a quick, long-lasting seal and provide a rough estimate of parts and labour. I prefer a punctual, tidy worker who can work for a couple of hours during the day.
