UK postcode to postcode courier calculator

Im quoting for a new client wordpress site for a courier firm in the UK. They want a calculator at the top of the home page where the client enters origin postcode, destination postcode and item dimensions and this gives out a price for the job. I’ve seen it on other courier websites but I can’t find a wordpress plugin that will do the job. Any ideas guys?

Using WooCommerce?

Made custom plugin for this what you need.
You will not find standalone plugin just for this purpose.

@Zaccc did you make this custom plugin? I am in the same situation as the original question.
Any help would be appriciated
