a page to display profile's most recent visitors - SE v3.20

I would like to create a simple page where users can view their most recent visitors. This page is only accessible to the user. This page will have the visitor's profile picture, their username, a link to their profile and the time when the last visited the user's profile. just a list, nothing fancy. The script is separated into three parts: the code to log the visitor's hit on the profile, the page that shows recent hits, and the log table to store these hits. SQL query needs to be optimzed for best performance. Max bid is 35 USD
