If you are already directly selling the ads, why not host them on your own domain? Then they won't be blocked automatically. If you still see people going out of their way to add site-specific rules to their ad blocker, the ads probably weren't as relevant or unintrusive as you thought.
Troy Hunt wrote about his experience with self-hosted ads a while ago [1]. Basically, he added a as-non-intrusive-as-possible "banner" (if you can even call it that) at the top of the content. Ad blockers blocked it. He changed the markup to avoid being caught by a false positive. Ad blockers (Adblock Plus with EasyList in this case) blocked it again.
I made similar experiences in the past, to the point where our API broke because we had the audacity to call one of our API endpoints "metric" (for a metrics service), which got caught by one of the over-zealous regexes of EasyList.
