Serbia importer company: Running Socks import

I am writing on behalf of our startup company, and we are interested in ordering running socks produced in Turkey.
As we are in the early stages of our business, we would like to begin with a sample to assess both the quality and the cost before committing to a larger order.
Could you please provide the following details:
Minimum Order Quantity (MOQ): What is the required minimum quantity for a full order?
Sample Availability: Is it possible to order a sample?
If so, what would be the cost and shipping arrangements?
Pricing: What is the price per pair for standard orders, and do you offer any quantity-based pricing or discounts?
