How do I protect my sources without using drop shipping?

Hello everyone,
I need a little help – I started a small company as aero parts broker. How it works is: I receive a request for a part, then I contact my suppliers and see who offers the best deal. Then I am supposed to ship the part to the customer (after purchase order). Now, until recently, I did ok with drop shipping. Suddenly, I have a supplier that’s refusing to drop ship, and I have a huge part to send from Asia to Europe. Now, I want to prevent the customer from knowing who the supplier is, and how much I paid for it. There will be issues like this in the future for different countries, etc. What should I do? Will forwarding company take care of this? Who bears the costs?
I’d appreciate some experienced answers.
Thank you.
