Prestashop Order output as xml file for external warehouse

Hello

I need to put automatically a xml file from the orders we get to an ftp server so the outsourced warehouse can get it from there and load it in their system.

Attached is the structure how it should look like. It includes customer data with delivery address and e-mail and order data with products, price, amount.


--> We use the newest version of prestashop.
--> I have no idea how much work it is, so please insert your estimated price.
--> I can send a sample of an xml file by mail.
--> Of course you can have the information in English.
--> Work should be done within one week.
