Make an SWF file transparent

Hi there. I am using a Flash world map on my website, which you can see at http://theworldblog.org. Every section of the website (which you can access by clicking dots on the map) has a different background color. Since I don't have the FLA file, I need someone to convert the SWF to FLA and make the background of the map transparent rather than white, so that I can embed one SWF file in all the different sections of the site rather than having to make different ones with different background colors. I'm looking to spend at the lower end of the budget range because this project shouldn't take more than ten minutes. Thanks.
