Need help getting a FLASH video player customized for use with online flv file playing

I have a adult video site, I need to get the .FLV flash video player customized to work. Currently, we have a basic player on a html page. But, we need this flash player to streaming instantly! At the moment, the player only downloads video at a certain speed. WE WANT THE ViDEO TO instantly be able to skip forward, backwards etc. etc. Our server is a Media Server, so I only think we need to customize the flv player for our needs. I need this project complete in less then 48 hours. Thanks,
