PHP driven profile page to be moved to a newer version of the profile page.

I have an old PHP driven profile page and have recently redesigned this. The HTML and CSS has already all been done and I have added some static content which just needs to be replaced with content from my database instead. Also there is just a bit of CSS work which still needs to be done so CSS knowledge will be required. I have a lot of the PHP code on another older page layout, so this can be taken from the old page and placed on the newer version of the web page. In addition to this, the new page needs a comments feature, the comments and respective user ID's should be posted to a table in the database. I have an 'Add Friend' button which also needs to be coded to work. I have a 'Message Me' button which should open a pop up window in which the message can be composed and sent. The old page displays the 5 most recently uploaded pictures, on the new page this should be changed to display the 7 most recently uploaded pictures. The new page has an 'About Me' paragraph which should be called from the database and displayed on the page.
