Sorting and comment system for existing script

I need someone to add sorting to an existing MySQL listing that users post. They post accounts, and they get added to a list. It is set by default to sort by Name, but I need sorting by each column. The user system is already setup, and I need a comment system added for each users page. The comments should list the members name, time, and message. Uploaded is a screenshot of where I need the comments added, and you can get a general idea of how the sorting is supposed to go. The main setup of the script is done, user logins, and the actual listing of data. This is a relatively simple project, so let me know how fast you can get it done. Any questions at all let me know.
