Need Joomla Expert [Specialist] Bug Testing and Fixing Browser Compatibility Issues

Hello, Timeline is 24 hours - 1 day YOU MUST BE AN EXPERT WITH JOOMLA. I HAVE HAD SOME WHO KNOW JOOMLA BUT DON'T SPECIALIZE IN IT AND CAN NOT FIX THE COMPATIBILITY ISSUES I have a website that is made on the Joomla 3.0 platform. The website does appear to display correctly on chrome, firefox and safari. However it appears to not display correctly on version of windows, such as IE6, IE7, IE8, IE9 and possibly IE10 I need someone to go to the site on these IE browsers and compare to properly displaying website on fire fox and fix found compatibility errors. Provide screen shots with browser version as before condition and provide screen shots for after [fixed] condtion. Also for each browser you must bug test the appointment booking button all the way through to actually booking a appoinment to ensure the process works correctly on all IE browsers.
