We have a Flash header/navigation bar. (Please see attached FLA files) There are two very similar versions of the Flash header/navigation bar -- one on the main page, one on the sub pages.
All we need is for you to add 1 tab to both headers. Very quick and easy job for a flash designer. The FLA files are easily to manipulate -- they were purchased from TemplateMonster.
Job pays $15. I am a Flash designer myself, and I know this will take you less than 1 hour if you know what you're doing.
