Edit an Exisiting WordPress Digital Asset/Content Protection Plugin -- 2

YOUR BID PRICE IS FINAL**NO LATER CHANGE IS ALLOWED**NO USE OF PAID API/SDK ALLOWED** I need an experienced programmer who can customize an existing WordPress plugin that can bring any webpage under password protection, email protection as well as subscription paywall. Should be easy to use. Should work with latest version of WordPress. The plugin is already made. The concept is: WordPress site owner can lock any web page of his choice. It can be unlocked in three ways: Password (already added feature) Email (already added feature) P a yP al Subscription (already added feature) You need to do the following: 1. Site owner can use the feature of Password protection, email protection and P a ypal protection simultaneously in different pages of his site. He should be able to mark the pages for password, email or paypal protection. 2. Site owner can collect emails for unlocking the page. For example, if a page is marked for email protection, visitor can simply put his email address to unlock. Site owner can see the collected email addresses for his pages from his dashboard. 3. Email address/password for download. By using shortcode, site owner should be able to protect a whole page or part of the page. Visitors need to put password (given by site owner) or email address to find the download link (Google drive/dropbox) or directly download from site. Site owners can let them download in ZIP, PDF, txt, docx, xlsx, pptx format (with 50 MB limit). Need to do this in part. Option to export all the collected emails in .CSV. Some small bug fixing, only if required. VISIT: [login to view URL] Please see the attached roadmap. I need full Source code and c o p y r igh t. Intellectual Property belongs to me.
