Customization to New_order email template

[Steveio]

I have a client who would like to customize the new_order email template that the they receive when a new order is placed.

They would like to know if you can add 'Product feature' details to the new_order email template.

They have 3 product features for all products which are;
Material: 
Range: 
Product code:

They would like to be able to add the 'Product code' alongside where the {items} information is displayed in the new_order template.

They do not want to provide access to their website to a third party but if anyone can supply the necessary amended files, they would be happy to pay for this. They are using Prestashop V1.6.0.14.

I have attached a screenshot of what they are hoping to achieve.

Thanks
