Create PHP Journal Application

I need a php journal application built. Users will be able to register an account and then create a new diary entry everyday which is saved by the application. Please see the two attached mockups for details. Features: - registration: login and signup. This is a paid application so we'll need to integrate [login to view URL] for credit card processing. User will enter email and password to register and then be redirected to payment page. - Diary. After registration user can create a diary entry. There is one entry per day. User can browse past entries. For adding an entry we'll make use of an auto-expanding text area. - Writing Graphs. A page inside the user area needs to display a graph that shows how many words per day the user has added. As well as the total number of words in their diary.
