566928 Simple Wordpress IP Registration Plugin

Hi, I'm looking for a professional programmer to help me build a simple Wordpress plugin. The plugin has to remember a users IP and when the same user tries to register a new account, with the same IP, a message should inform the user, that there is already an account registered with that IP - Exactly how it works now, when you try to create a new account with the same email. If you have any questions, please let me know.
