Dear Sir/Madam, I am looking to buy 100 - 200 m2 of 1cm thick polished light grey G603 tiles. Dimensions 1cm x 30cm x 60cm for a building project in New Zealand. Could you please advise price, lead times etc. I also wish to discuss having a small sample sent (I am happy to pay for the cost of this), and will be travelling to China in about 2 months to visit the factories we will be securing building supplies from. Regards, Gavin Holley
