Boxing Beginner - Adult

So I've decided to take up boxing. I'm 25, 6ft 2 and weigh around about 70kg. I'm not delusional and know i have no chance of competing with other boxers my age in competitive amateur competition. But i would like like to compete in the novices if the trainers think i will be ready (Maybe have it as a goal to train HARD and improve for). Anyway I wouldn't just join a club for the sake of keeping fit and using up the time of the trainers and the equipment, as I think that would be unfair to the other fighters who are actually fighting in competitive championships. So i have a few questions;

does anyone know any boxing club around the Meath/Dublin area? I know theirs one in Navan but my barber went their as a beginner and said they really don't give a **** about ye as an adult, they basically just put ye in a corner and focus on others (Which i can completely understand) he left after awhile.

I heard theirs one in Ashbourne that would be ideal to where i live does anyone have any information about the club? Do they take adult beginners, etc... any info would be great.

When are the Novices held, Is it a high level of standard?

Finally what do the boxing people thing, am I too old to join, do you think trainers will give me time if they know i want to compete and not just do it for fitness

Thanks, sorry if these questions have already been asked, not arsed flicking through threads.
