Ad Space for Leaderboard Banner on Wordpress Website

I need advertising space above my slider and below my website menu. I need a 728x90 leaderboard ad space with off white padding like my slideshow, and two button ad spaces with off white padding to the left of it if they will fit ??x90. If two wont fit than one ad to the left is ok. The spaces need to be easily accessible for me to insert ads into them preferably a widget. An example of what I want is at [login to view URL] and I have also added a picture. My website is [login to view URL] and my subdomains are [login to view URL] and [login to view URL] and I have also added a picture of that. They all use the same template and are wordpress websites.
