Simple Slicky dating Site -- 2

Hello Guys I want a simple dating site based on credits . Visitors will visit the website and create their account putting Gender, Height, Age and Town. Upon login the Visitor will be able to browse through profiles and filter them against the Simple Parameters above. They will login using their email addresses. For each login, a Visitor is supposed to enter his/her email and code is sent to the email, which they will use to activate a login. Each contact will have an automated username for display only which should be numerically linked to the Primary key e.g. if the record is 459993, then username is 459993. In order to contact a profile, the user must have some credits( Each letter in a message will cost a credit) which must be loaded through a payment ([login to view URL]). 25 Credits will cost $1.
