I need a lawyer for a divorce

I have been going through mediation for the past 12 months but my wife is now dragging her feet. The last offer I made for a division of assets (58/42 in her favour) she rejected out of hand. I need to speak to a lawyer about my options. She lives in Galway with our two children, and i am a British citizen working in Saudi Arabia. I am paying her monthly maintenance, but need a divorce quickly as without one, I cannot commit to buying a much needed property. Once I hear back from someone, I will share further details of our assets.
