CSS Edits for IE compatibility

Hi, I have a website that has valid CSS markup, so looks as intended in latest versions of Firefox, Chrome, Opera etc... but is broken in all versions of Internet Explorer. I require some custom targeted CSS stylesheets for IE8, IE7 and IE6. It needs to look perfect in IE 8 and 7 though am willing for *some* flexibility in IE6 as long as it is reasonable (it's still annoyingly a high % of our traffic). I only require one page - the homepage of the site doing (as same design elements are used throughout the site). If there are any other browsers that I want targeting (such as earlier versions of FF), I will address these after IE - so please base your bids on 3 seperate stylesheets (IE8, IE7, IE6). If you are interested just send a message and I'll send you a link to the site so you know what needs doing **before** bidding. Many thanks.
