Hi Carrieann, Huskerdu is right, however to try and help you are prob looking at a minimum €25/30,000 (incl honeymoon) for something decent to be remembered.
I married an Irishman in Italy (my country) in August.
paid for 110 seated and for 70 at the evening reception. went almost 4 weeks on honeymoon to hawaii and the whole lot cost us about €30K (incl us paying for the first night in the hotel and for all bus transports from the airport, to the church etc for the irish guests).
we paid €70 a head for the meal (min €100 in Ireland) and €25 a head for the evening reception (again min €40 in Ireland), we paid €400 for the Italian band and €450 to get an Irish band in too (between the two the music was on from 8pm to 2am).
the cake was €0 because in italy the restaurant provides them (we had a choice of four flavours and endless shapes, they also gave us the topper figurine free, and the best part of all, it was gone within 20 mins....the irish especially loved it, my father in law alone had 7 blooming slices!!!, it was a millefoglie, millefoille in french, delish)
dress was fab italian hand-made yet was the cheapest i found at €1250.
the church flowers cost us a lot at €1000 but that's because italian churches are dressed to impress at weddings (and that price was a family friend discount !).
the only thing we spent most money on was the photographer + video at €2500 (pretty same as in Ireland, but the album + DVD are digital novelties not to be found here....dying to get them).
we didn't fly first class (we'll do that when we are pensioners

) but the hotels were all 4+* and 5* (you need them after a year planning).
So it really depends on your needs and what you want to remember most.
eg I was going to give up on a lovely merc for transport but my mother in law convinced me to get it in the end for the sake of €300 because she said she didn't want us to regret not having done this and that.
so think carefully what you give up on, but remember it's only one day at the end of the day.
what really makes it are the guests.
i have been to a few all irish and all italian weddings and by god are they all the same boring lot?
i am sorry to disappoint you but every bride ends up spending more then her peers trying to add in things that make her own wedding stand out...but in the end they are all the same aren't they?
i was lucky cause with the 2 cultures meeting neither party was at all bored (they all had something new to experience) and the day was a novelty of different uses for all to enjoy.
so my advice would be:
1) getting married abroad is still costly but you get more value for your money (however if you are not a foreigner it might be daunting so you defo need a planner)
2) i thought the irish would have hated the irish band (we got it for the italians really) but they absolutely loved it, so get one...even if you get married in ireland
3) classy doesn't have to be posh. we got married in an agriturismo (like a farmhouse/ranch with chalet style rooms) which everyone regarded as the most beautiful place they had been in. so ditch the big posh hotels, sometimes you may find real class in a countryside setting.
4) the best were my sandals (august roaring hot wedding) at €12 (love them!!). the only person who knows they were €12 is my mum. everyone else thinks they were fab and they look brill on the pics. and my necklace was my mum's too (you need something borrowed after all

)
5) my auntie likes flower arranging so my bouquet cost €0. She got the begonias from her garden and the roses from a bunch i got as a present from a neighbour. the ribbon was from strips i asked the dressmaker to keep. it lookes great on the pics and it ended being thrown in the crowd anyway.
6) get yourself a foreign fiance to have a guaranteed good party where people don't need booze to have a memorable night

(maybe farfetched)
i am sorry i could be talking about this for days.
hope i have helped somehow.
