App or code to allow customers to calculate transport costs on the website

Question:
We are a car import company based in Belgium. Our business model is to import cars from parts of Europe to Belgium. We would like to allow the customer to calculate the total import costs on our website, including transport costs from A to B and other costs. Does something like this exist in Wix, or are there developers who can make this for us?

Product:
WIX Editor

There is a calculator builder app in the Wix Marketplace that may help. If not then it can certainly be custom built.
