I want to make an application for a international shipping company

We are an international shipping company that imports from several countries such as China, Turkey and others to our country. The application is an integrated system that allows the customer to obtain the addresses of our stores in each country and each customer has his own address or code to enable us to identify his shipment and also the customer can track his shipments through a special control panel Each customer can see the number of shipments, are they in the warehouse, on the way, or have already arrived at the importing country, the weight and size of each shipment and the amount to be paid as shipping fees, providing an electronic payment method and also a shipping price calculator that provides approximate prices for the customer, where he puts the country, size and weight of the shipment and then The approximate price is shown to him, and this makes it easier for him to obtain prices instead of writing to us to get them and other details that we will discuss together, God willing. I want to know the approximate price and duration, and I also want to work with a wonderful UI UX Design.
