Dynamic Google adsense adds on my Joomla site

I have google adsense Account and i have adds at only two places in my site [login to view URL] 1) At forums, where a default adsense add is created for every new forum post. [login to view URL] 2) At Blogs, where a default adsense add is created for every new Blog post [login to view URL] Now i want to increase earnings through google adsense and would like to add google addsense at other places in my site without affecting the professional look of my site. Requiremnts: 1) To identify areas in the site to add google addsense adds. 2) To create google adsense adds at identified areas. Note: No Server access is given, you have to guide me for adding google adsense code via skype or Teamviewer scrensharing tools. Payment is only released after successful completion and analyzing the traffic and clicks for a week. Good vendors with right attitude will be considered for future developments on the site like SEO, Font finalisations, facebook pages, adds module enhancement and development and other changes and developments on the site. Thanks
