WordPress PDF Sales Setup

I already have the PDF and a functioning WordPress site; what’s missing is the buy-and-download experience.
Here’s what I need you to put in place:

• Product page: create a clean, conversion-friendly page that highlights the PDF and its key details.
• Payment gateway configuration: enable Credit/Debit Card and PayPal so customers can pay in either way.
• Checkout flow: allow buyers to check out as guests—no account creation required.
• Secure delivery: immediately after a successful payment the file must be available for direct download, with the link protected from unauthorized sharing.
• Basic test order: run at least one sandbox transaction to prove the flow works end to end, from payment through download.

I’m open to whichever plugin you feel is best suited—WooCommerce, Easy Digital Downloads, or similar—as long as it stays lightweight and reliable. Access to the site’s admin panel will be provided, and the PDF is ready to upload the moment you start.
