Prestahop 1.6.1.9, delivery note to be edited.

Hi, I need an edit in the delivery note that you can find and download in back end > Orders > Orders > click on the lorry icon > it will create in PDF a delivery note. 1. This note should have deleted all address of the customer and Payment method row. 2. Instead of the address of the customer should have the first 6 digits of the company name of the customer. 3. At the bottom of the page should be present: page 1 of 2 - [the first 6 digits of the company name of the customer]. 4. Delete Reference column and put instead of this the Quantity colums which must be move from the right column to the left column.
