I am looking for a Doubleclick for Small Business (DFP) expert to setup ad units, channels and placements to maximize ad monetization. The site on which the ads will appear has 9 categories and a homepage that can be separated into channels as you recommend. All non-mobile pages currently display one 728 x 90 leaderboard and two 250 x 300 medium rectangle AdSense ads. Mobile pages will need to display one 320x50 mobile leaderboard and two 300x250 mobile rectangles. Advertisers should have the most granular options available to make the site's ad offers as attractive as possible. Open to additional suggestions. Thank you.
