Thank you for the compliment there! Appreciate it.
Regarding your question, the sales page they usually give you is in HTML and intended to upload to your web host via FTP.
There is a workaround that I just considered.
1. Install & Activate Elementor
2. Create a new page, and choose the canvas page template (this removes the header and footer)
3. Use the html element and copy/paste the html from the sales page from the PLR
You will have to manually upload any images and fix the URL to the images.
