Create Excel quoting tool

An excel document that holds large amounts of background data based on multiple european agreements (rates) for a transport company. We want an operator to open the document select a country and delivery postcode within that country, select a collection post code in the UK and enter in basic weight/dimensions of the shipment. combine this with multiple rate cards that make up the cost of an A to B shipment to produce a cost price to transport the goods that can be used to quote customers. Document attached provides a good starting point but its outdated and i want it to be more attractive, on going management of the document needs to be trained out to an internal team also within the quote.
