Adjust Flash applet to have different display sizes

We have a Flash applet that displays text and images that it gets from xml files. Currently the display is 160 pixels wide. In this bid we want the applet adjusted to have 3 possible display sizes, and the display size should be set in the flashvars in the page the applet is in. We have an old version of the applet where the display was 728 x 90 pixels. I can provide the source code for that version if that is helpful. I've set a three day deadline, but if you can do it faster that will be great. If you would need more time please bid anyway and let me know how long you would need.
