127889 MySpace clone script

I am looking for a MySpace clone script. The most important part of this script will be my ability to limit what types of files can be uploaded. In other words, I do not want people to upload any .js files, exe files or .mpg files. If possible, they should only be able to upload .jpg and .gif files. I also want this script to have the ability to detect any javascript in any user files (profile, etc) and not allow it. Obviously I want to avoid any types of exploits from being on the server/site. I'd like to be able to customize the main page with my own header and logo and colors, and allow people the ability to do the same with their profile. If you think there is a pre-made script that you can modify to meet my needs, let me know and I'll purchase it and you can then modify it. Lastly, I want the ability to personally approve each profile before it is posted and edit if need be. This will not be a huge community.
