Serious formatting problem in IE with my site

Hi,
I have build a site www.mymedicenter.com and everything looked fine till I was looking in firefox. But when I saw it in IE,Nothing was at it's place. The copyright is at the middle of the page. There is tons of white space at the bottom, I don't know why ? The site is looking ugly like hell and no wonders I am not getting any visitor. Who will visit such site

I am not able to understand from where should I start and what exactly to do ? Should I use lot's of tables instead of all the div to fix everything ? also in IE, when I I increase the font size, the left menu comes at the bottom.

Thanks

 

I see the same page in Firefox, IE and Opera, with minor changes but looks fine to me.

 

Well I fixed a couple of things but still, does the "copyright" is at the middle of page ? also doesn't the length of the page is excessively long with huge space at the bottom ?
also the color of links far better in firefox than in IE. any suggestion, what I can do about it ?

 

Everything looks ok, there is some white space on the bottom...you have about 5 <br>'s in there..
