Customization of script.

Hi, im searching a freelance that do the next: Customizing the script x10media mp3 ([login to view URL]). I want the site to do his function: Download music. I want to reduce the script to do just that, eliminate the things that make the script slower. I want to reduce the loading of the site and the server. Some things to do: Delete unnecesary sections and parts(As part of Lyrics and other things). Minimize the requests to the database. Optimize the code if is necessary. I'm looking to make the site faster and stable. Sorry for my bad english, natively i speak spanish.
