Small task - Need help with swf file that needs to have transparent background for powerpoint presentation

I need someone who can help me embed a small looped swf file into a Powerpoint presentation with transparency. I have a swf file which when I import into a powerpoint presentation has a white background, I want to get rid of this white background so that the same animation plays with transparent background in any powerpoint file. Need it done within next 1 hour. Thanks Milestone will be released once all the source files are handed over to me. Budget $ 2.50
