We have an Ecommerce website powered by zencart. Two features need to be added to the website.
1. We have the option of sending the 'delivery confirmation' email once an order has been delivered to the customer. We want to customize this email. Specifically we want to
a. Have text of our choice in that email.
b. Have a link in the email that will direct the customer to a 'feedback page' on our website. The feedback page will have to be added to the website. It should have a 'thumbs up', 'thumbs down' and 'just ok' options to choose from. Please note that this feedback about the order for which delivery confirmation was sent. Customer should also be able to add comments in a text box on this page if he wants.
c. Finally we should receive this feedback as an email message and we should also be able to see list of feedbacks from the admin side.
2. Add a greeting message (about 20 words) to the default invoice .
