Dreamweaver site fixed and vista explorer 7.0 compatible

I've made a site in dreamweaver. Fairly simple site! It was completely done, I was getting ready to complete the whole thing and then I don't know what setting I have changed or what is going on. I'm fairly new to dreamweaver, but the site is just falling apart! [login to view URL] I need it fixed for the customer. I've done all I can do!! It's driving me nuts! It's time to hand it over and get it fixed by a professional. MUST know HTML to fix this. I will send you the whole website file via FTP including html and images. Can you read through what I have and just make it look right? It looks good on firefox and internet explorer, but my customer has internet explorer 7.0 on windows vista and he says it is all messed up. It's impossible for me to see what it looks like and we are having to talk back and forth and he always says its still messed up. HELP! I'm not getting paid much for this site so lowest bid will be most heavily considered.
