Hello Chris,
It's good to hear that you and your wife are planning to renew your wedding vows in Ireland. I'm sure that it will be a wonderful occasion.
There's a very useful page on the Ireland.com website that gives
wedding tips, which you may find helpful. There are also a number of related threads on the Community, where you may be able to draw some ideas from. You can find these threads
here,

Perhaps, some of our industry experts here will also be able to provide you with some information that will prove useful to you. I wish you and your wife all the very best.
Regards,
Eoin
