Expiring Links - X Minutes after Click = Expire

I want to be able to provide unique links to my leads via email that once clicked will expire or redirect to a new site within X minutes. <[login to view URL]> -> <[login to view URL]> after the 1st click the link expires or redirects within 5 minutes <[login to view URL]> -> [login to view URL] This is to prevent the link from being shared with others. I want to be able to generate X unique links and export to a file or use something dynamic like... [login to view URL]@[login to view URL] Please submit your bids and how long it will take you to complete this project. This is similar to protecting a download link with [login to view URL] for example. ------------------- PROJECT EDIT: -Usage Explanation (This is not required to bid but is something I am very interested in) As of this moment I plan to export these links to a GUI desktop based autoresponder and reply to each new lead with a unique expiring link. I was wondering if it was possible for you to take this even further. I'd love to do this all on the server without having to use an autoresponder desktop application. Could you do the following: 1. Receive Incoming Email -> Add email address to database with timestamp 2. Generate expiring link based on filter (what email received the message) 3. Reply to email with a message based on template / filter that includes the unique expiring link 4. Add response rules -> Respond to the first message only -> First email received = trigger template1 -> Second email received = trigger template2 -> Third email received = ignore -> Manageable delays 5. One-Time mailings at X emails per second 6. Send / Receive Configuration -> Receive email from X email accounts (hosted on server) -> Send email from X email accounts (hosted on server)
