Ads not loading via Google and other conflicts for Joomla 1.7. Need help ASAP

I have had a sudden burst of Joomla conflicts: -google adlinks don't seem to load anymore -google ads barely load all of a sudden. and if they do, its random -have been told of jquery conflicts -have been told of plugin conflicts -have been told of javascript conflicts -facebook chat modules spit out errors. -registration page spits out an error I need someone to scan through website and fix errors. website: [login to view URL] I really only want to deal with people who are good at fixing these things.. I have wasted PLENTY of money and time with inexperienced people in the past and need an affordable solution, and quick.. Hoping that you know what you are doing, and how easy something like this is to fix.. It should be a win win for both parties.
