550653 Wordpress plugin Popup gatekeeper

Hello everyone, I need someone who can create a wordpress plugin that displays popup window similar to [login to view URL] or [login to view URL] but with the following features. Should be always on top like actionpopup but no close button. 1. The plugin should have a password field where the user has to input password to remove the popup. If the visitor has the password, store in cookies and the user should not see the popup until the password expires. 2. Admin should be able to create passwords at the backend with expire dates. 3. The popup should display to users of a particular country/countries (say. UK or Norway) admin should be able to set this from the backend. 4. If the user does not have password, he has to wait until specified seconds for every post he tries to read. 5. The popup should be unblockable. 6. the plugin should be easy to integrate with any wordpress theme. 7. Ability to exclude particular pages / posts from the popup.
