Adjust Website Code for IE6 and Standards Compliance

I am a front-end web and graphic designer who really shouldn't be doing any coding. But, for a friend of mine, I took on a project and did the coding for it. The website is finished (URL below). It functions without problems on a WebKit browser (Chrome, Safari) and for the most part on Firefox, but it is has problems on all versions of IE, the worst, naturally, being IE6. I do NOT want the website to change in function, I just want it to function like it does in Chrome/Safari in IE6 (as much as it can). So--I need to get this website up by Monday, and I've becoming incredibly tired of trying to make this work in IE6. I'd also like it to be W3C standards-compliant (my code, without a doubt, is BAD). The site is full of Javascript and JQuery, and its design relies on only one HTML page--this should be an easy job for an experienced web developer. If the work is timely and the communication is good, I might have larger projects in the near future. You can view the site in its current form here: [login to view URL]
