PHP script help for a login subscription site

I will pay $30 for this work. For someone that knows PHP, it should take less than 1 hour. I am using a PHP script called Isubscribe ([login to view URL]) for membership subscriptions. I installed it, but I am having some issues integrating it with my site. I need someone who really knows PHP to help me do four things: 1. Protect a PHPBB forum using the protection script from Isubscribe. 2. Correctly code a login page so that it takes you to a protected area once you login on the login page. 3. Figure out why the cookies are not static and why you have to re-login each time you open and close the browser. 4. Figure out why some things don't work like the logout feature.
