css tableless & browser compatible

Hi, I am looking for a experience css coder and joomla expert to make my website browser compatible ( IE 6 & 7 / Firefox / Opera ). Please inform me what it would cost to make my site tableless as well. If there is an option to make the whole site valid ( it's hard as this is a joomla site ), please tell me. Please state in your bid ( by pm ) what the seperate services will cost ( browser compatible / tableless / validation ) Happy biding ! The url of the site is : [login to view URL] Kind Regards.
