Funny you mention 500 euro, we had a painter do the EXACT same on us a couple of years ago.
Small guy, drives a big grey car and says he is from Dundrum by any chance?
He never came back. i ended up doing it all myself and cursed him every brushstroke!!
That said i learned I could do it myself and have since done the soffit and facia boards outside myself which i was planning to pay someone to do beforehand and in the summer will tackle the outside of the house myself, so a slight positive to take from the experience!
