Add a PHP/MySQL login script a website template.

I am crating a replacement to this website: <[login to view URL]> I will upload the template to the winning bidder. 1) When a user goes to the member's page I would like the user to be able to click on any of the members and have it go to their own business profile page. 2) Members should be able to login and edit their profile. 3) New members/accounts should only be able to be created when a private invitation is sent to a new members email address though the admin section of the website 4) The admin should be able to add and remove things from the calendar page (a new calendar will need to be created for this)
