I seek a freelancer to compile a zipped dataset comprising a collection of TXT PDFs, meticulously organized within a structured hierarchy. Your primary objective is to download every PDF from the specified pages and arrange them in a coherent folder tree. The final deliverable should be a ZIP file containing all PDFs, ensuring that each document is included, directory paths follow the brand/model/type format, and filenames remain intact. You may employ a script, scraper, or manual download to fulfill these requirements. Additionally, please provide a concise note in TXT or Markdown format detailing the methods employed for future reference.
