Validate Website HTML/CSS Code and Make My Site Firefox and Internet Exlorer Friendly

Take my website and make it compliant in both firefox and Internet explorer. Validate the html code, whatever you need to do in order to make the site look correct. The design looks correct in Internet Explorer. It is all messed up in Mozilla. Make the correct Internet Explorer version look the same in Mozilla Firefox. The site was edited in Frontpage 2000 (bad mistake). The site is using html and css layout with some small javascript. This should be a quick and easy job for someone who knows what they are doing. 24 hour turn around time needed please. Total of 8 pages. Pretty simple task. I have the original template that is unmodified and untouched and not messed up in anyway that looks correct when I use Firefox and Internet Explorer. All you need to do is take the content - the text - from the active website while viewing it in internet explorer and copy and paste it into the template using a program that doesn't butcher up code like what frong page does. I started using NVU html editor. This should be fast for someone who knows what they are doing.
