You could try the Dental College at Trinity, you can elect a student or prof to do the work.... I had similar work done, it took a bit longer than a normal clinic but the student you will get for that type of work is usually qualified and furthering their career with restorative dentistry.
I had 2 veneers, one post and crown, and 3 crowns and the whole lot was under €2000, that is 2/3 years ago. You just turn up at the clinic and have a general examination, tell them what you would like to have done and they will make an appointement with the relevant dept.
Good Luck.
