How do I set up a separate bank account for my business?

Question

I have registered my business last year and have sent two trial shipments to Pakistan consisting of grains and seeds. The company in Pakistan would like to order bigger quantities but i have been unable to open a separate bank account for my business.

Because this business involves international payments i also haven’t been able to get the invoice payment for the trial shipment into my personal bank account due to the State bank in Pakistan not allowing a business transaction going into a personal account. How do i resolve this issue and why am i experiencing difficult in opening a business account for this business since i have another business account for another business i have and it wasn’t a hassle at all.
