Hi Alri, what part of the south east? We had a similar job done in north Kilkenny that we were quite happy with - I can give ye his details if that's in the right area.
I'm not sure if he works in these areas alri but the builder I used was Philip Carrol and his number is 0872756975 if ye want to check with him. Probably a better bet is to speak to people in the area for local recommendations.
