Recommendation For Family Mediation In Dublin

Myself and my wife are separating, and we wish to go for mediation. I understand that there are three different mediation services in dublin, namely the Family Support Agency (free, but 2 month wait), AIM Family Services (€70 per session), and the Clanwilliam Institute (€180 per session). Could anyone advise my of which of these three would be the best? Our circumstances are complex to separate, and there are several children involved as well.
