Customized code for: Giftbox Addon & Personalized Gift Message (Export as PDF)

We want to have a full personalized and customized solution for our Gift Box add-on, with a personalized Gift Message during the checkout, this solution should work lifetime, without renewing any license of 3rd party contributors. The hired programmer/developer is liable to setup all add-ons and features. Everything should work 100% and free of any bugs and issues. The add-on should match our psd’s. The Gift Box add-on on the right side of the product page for the different caviar types is always at the same place and responsive, as well as working for mobile. The Gift Box thumbnail is not full visible until the customer decides to "Add Giftbox" with the checkbox. The gift box thumbnail has always an on click popup with 2 columns - Left side is a picture (slider with some images) right side is text – popup is responsive and fits to mobile. Example: If customer adds 4x 50g of Caviar + click on Add Giftbox on the right side of he caviar product page and then presses the add to bag button -> 4x Caviar and 4x the correct size of the Giftbox will be added to bag/cart. (Popup design and Slider is existing) We should be able to replace the pictures in the popup slider and we should be able to replace the text. Textcolor is #333333 The Gift Box will be listed separately in the cart/checkout, so the customer can add multiple customized messages. The total price is always changing to the correct amount of added gift boxes. "Add Gift box" is a little bit cheaper then the normal Gift box in our shop. The solution could be anchoring simple products for the add-on. During the checkout, the customer can add a personalized message with each gift box he is purchasing. The customer’s messages will be saved in the checkout system. We get the correct PDF with the correct size of the personalized message for each product listed in the confirmation mail. The personalized message has different topics & always the same static background on the left side + recipients name + senders name + the message & telling how many characters are left. The personalized message has a live preview on the left side and on the right side the customer is filling out the „form“ fort he customized message. The font for the personalized message will be converted live with CSS, jQuery, JS etc. as a preview on the left side, while the customer is filling out the form on the right side. The customer should be able to add a personalized message for each Gift Box he added. We should receive the customized message, anchored to the correct gift box in our confirmation order as a puff with the correct size, so we can just print it out. The gift message should be saved, so the customers can review it. In the end the hired programmer should give us some time for small design and functionality changes regarding the feedback after he finished the project to receive the full payment. _____ Please read the detailed Scope.
