White-Brined-Cheese Turkey Import and Export Companies

I am a Tanzanian studying in antalya Turkey and someone from Tanzania wants to buy a minimum of 1100 pcs of cheese from here( white cheese for the remainder) and i dont know where to start or who to look for for the whole process The buyer is so serious about it and after the first buy he looks to be doing the same sales for a long time so he might be a repetetive buyer
