Add/modify 7 functions in my Prestashop Dropshipping module (Spain supplier)

I have a dropshipping prestashop module, it is currently operational and works with API with my supplier in Spain. My version of Prestashop is: 1.7.6. My PHP version: 7.2. My server is dedicated and is very fast! The current module is only compatible with Prestashop 1.7.6. I will provide you a dedicated server environment (for making your development and test) the server is hosted on Godaddy India, all features is available for your work: Domain, SSL, Email, Centos, Plesk Panel… I want a job within 7 to 8 days maximum. You need to be able to work with API and added a Chrome/Firefox extension to complete this job, so please take this into consideration ! As it is indicated on the Freelance site: "You should not pay for a job until it is finished and you are not 100% satisfied", so please note that everything is in compliance with the Freelance site, I would not pay any money in advance, nor even during (millestone) the work etc ..... I would only pay you at the end of the work and after having checked that you have made my requests. 100% and that the module works correctly and without bugs. The work you need to do: 7 features to add or modify (depending on the case I ask you) in the dropshipping module that I will provide you (zip). 1) Modification feature: Products create method. Actual module is import / create all supplier products with attributes / options (example 1 product is imported with somes various colors in the same product into the Prestashop. I want that you modify this method. For example i want that the module import / create 2 differents products into prestashop (one product with color red, one product with color black) so module need to add colors / options / attributes into the end of prestashop product name with French language (available by supplier API). 2) Modification Feature: EAN codes. Actual module is imported EAN (13 digits code) of the suppliers products without giving me the choice if i would IMPORT or not this EAN code of product: I would that you add a function that i have choice for import or not EAN code of supplier. 3) Adding feature: SKU Rules: This new feature will be used to modify the SKUs of the supplier during creation in Prestashop. The reference SKU of the Prestashop product will then be modified (with this function) when creating new products. 4) Modify feature: Supplier order informations Windows. In the center of the page of a Prestashop order details page, The actual developper has added 2 windows of Supplier information (for the orders sent and order tracking information). I want you to change the display method here from these 2 long Supplier Windows to be replaced by a single Windows (square) and need to change the position of the Unique Windows after. 5) Adding feature: New POPUP Windows (Before sending the order to Supplier) In Prestashop Back office admin order Detail page: The Windows square (see the step above) : I want you to implement (create) me a new Windows (POPUP) and that will open when we go to click on the "Send Order" button. In this Windows POPUP, it will be necessary to implement functions which will be used to modify certain things before sending the order to the supplier. For example, change the carrier, add a note attached etc... 6) Adding feature: New extra method to Import Products from supplier product page into Prestashop (With Chrome/Firefox extension): Like some extension for Aliexpress available actually. 7) Adding feature : BLACKLIST PRODUCTS: : Sometimes need to add somes products into a blacklist (added for example by me), so the goal is for not import/or synchronise stock of this products added on a Blacklist because somes products are prohibited for sales.
