WooCommerce E-Mailtemplate Customization

---- FIRST OF ALL AND IMPORTANT ----: 1.) This has to be done until Saturday Evening (German Time: 17.00 o'clock / 5.pm.) If you can't solve this issue within this time: Don't bid on this 2.) You are not allowed to install any kind of plugins to do the job. We need this to be hard-coded inside the php-file. The only exception is to have a plugin for previewing emails. Here is the Issue: 1.) We like to customize the [login to view URL], wich is already inside a child-theme folder and works fine there 2.) You have to do this on a live environment. 3.) Please see attached files. Most of the stuff is just adding some Text and and call up some already extisting variables 4.) The most complex thing is to send the [login to view URL] also to the "Anbieter (Vendors)" in CC. For the "Anbieter(Vendors)" Informations we use ACF and generated a Custom Post Type, called "Anbieter". For each and every Product we can display individual "Anbieter(Vendors)", so the customer knows where he get his product after every auction ends. 5.) Even if there is a complex auction platform beneath, this shouldn't stop you, cause at the end everything is just a normal woocommerce process. 6.) You will get: FTP / MySQL (if needed, but we don't think so...) / WP Admin and a already buyed product as well as a demo-vendor for testing everything. Attached some files you should take a look. Inside the [login to view URL] there is only the thing missing related to the "Anbieter(Vendor)". The [login to view URL] was generated with the plugin Woo Preview Emails. You can ignore those "UTF-8" Issues, cause they don't appearing inside the real mails.
