research and Banking for import export

I’m From Bangladesh. I do import Nutritional Supplements” Products USA brand wise for Bangladesh market.
I do start import from 2016 to Now! I’m Authorized Only one importer of some USA top Brands for Bangladesh Market .

Another important point is All USA Brands want Advanced total payment for arranging any Shipment.

From USA to Bangladesh sea port every Shipment takes approximately 45 days, another 45 days I need to sale my total package and transfer the payment to Receiver Bank
( Which financial company will finance).

I need you to find out well known financial company’s who will give me financial support to make advanced total payment done to my USA exporter for my shipment and they ( Finance company) will take a minimum fee from me for this service and they give me 120 days to transfer their total amounts to them!

I want you to research and communicate the finances company and my USA exporters to finalize the perfect way.

I’m giving here a Demo Bank link who is providing this services, But you should research and find out the perfect service providers for my company! https://www.exim.gov/tools-for-exporters/exposure-fees/shorttermelcessfinancing

Thank you so much. All the best!
