Changes needed for a website to make it work in Ie6 and various other changes

Client has asked us to make a website for them static site and then it can be integrated into an ASP CMS website. It has to be CSS powered and work with IE6, 7, 8 and Firefox. After 4 revisits to do this I am asking if anyone on RAC can do it; we don't have IE 6 anymore, and the designers in India who said thy can do it clearly over exaggerated their skills. There is more details on the latest lot of changes, this MUST be done today or Saturday so ready for Monday.
