As posted elsewhere Jojm is a superb plasterer, highly experienced and very good. And will either just get on with the job or, if you wish, have a good chat with you - he's a Dubliner so very friendly!
I have either used him directly (once, for a biggish job, a couple of rooms, insulated plaster boards and finishing) and twice for neighbouring landlord where I arranged and saw his work completed expertly and efficiently. Recommended. He loves dogs too. If relevant...
