Chnages to My Dating Website

I have a dating website, which is not currently up yet, as i need some more features to be added aswell as changed. The website is a clone of Face-Pic.com. So please see there website if you are unsure about anything. This is what i need to be done: 1) Register: The register questions need to be changed. 2) Login: At the moment, its using the users email address as the User login ID. I want this to be changed so that they can use their own nickname for example as their login ID. 3: Viewing Profiles: I want it so that when a user wants to show someone their profile. i want the link that they pass on to their friends to be [login to view URL] At the moment its saying id00031 counting upwards... 4: Messaging: I would like a messaging system to be added, so that users can send other users messages. 4: Some pages: I need the template to be included in ALL pages. There are a few pages that have the previous look which i cant get rid of. 5: Premium Tools: I need a setup that users can pay for (Premium Tools). Incase they would want more pictures to be displayed on their profile, or to be able to send more messages a day. 6: One more last little thing. On the front page, i want the top 4-5 latest online users pictures to be displayed. So that it updates itself every so often. I can only pay $30 once the project is complete, but can pay out more money once the webitse is earning. Once placing your bid please state the amount you would want paying when the site is earning money.
