In the end I went with Annette O'Sullivan in Ballincollig, and have found her to be of great help so far. I tried one crowd (Edward Carey & Co) inside in Cork city first, but they were busy when I rang, and took my contact details and never rang back, so dropped them like a hot potato and haven't looked back since.
Annette gave out a little document for what you needed to do, and was very quick responding to many questions via email so I'm happy to recommend her.
Looking forward to getting the process finalised now and getting the keys !
