Arabie Saoudite Demandes

I want to order 1200 cartons monthly each carton has 500 pieces of metal hangers (galvanized cloths hanger). I Wanted to ask about the following: 1. How much for shipping to Riyadh? 2. Can you sell a carton for 5$? if not please tell me your lowest possible price. 3. Do you do custom Packaging? I'm a reseller in Saudi If we can come to an agreement we will be ordering big amounts monthly. Thanks,
