youtube to mp3

i want you to make a similar site like this link provided: [login to view URL] it should convert video to mp3. the website should run fast. i know it is up to the server but it is also up to the code. i want add banner on each side of the download link of mp3. I also want admin panal, it should have all the basic options. like bann ip, turn the website offline. message on top, add banners, . this script should be advanced enought to keep the mp3 in the database when it is converted. it should disabled hostlinking. meaning other webmasters should not be able to link directly to mp3. user should always come first to my site and than click on download mp3.
