your best just doing adds in-house dude there are 2 ways to doing this the free way that takes time or getting the banner ads module and setting up your payment gateways for the ads service if done the free way or setting it up with in the banner ads application benefits you make 100% profit give or take google on ad-sense takes like at-least 75% of the ad revenue you get sometimes as low as 10% and sometimes as high as 25% one thing google has to it is its taking the advertising on so you don't have to really its just automating your ads but with selling ads you can focus on you niche and set the rules for ad requirements that we will only accept ads from this sector of the market so on so fourth anyways hope any of this helps

No Thank You.  I've had another big website for 20 years and did the in-house advertising thing. It's nothing but a huge headache.  Sold that site and now have smaller sites with adsense only.  Much more efficient and can focus on content rather than sales.
