Serbia imports Employee Shirt

My name is ******, and I am responsible for the retail chain of ****** bookstores in Serbia.
I am reaching out to you with a request for the procurement of clothing for retail employees, specifically men’s and women’s shirts in sizes that I would provide at a later date.
The estimated quantity is 1,200-1,500 pieces.
I would kindly ask for your price offer as well as the estimated delivery time.
Thank you in advance for your response.
