Can anyone recommend, a program for me.

OK, here is the situation.
I am seriously considering putting PPC ads on the old posts of my blog.
right now, I have over 7000 pages indexed, in 13 languages.
The front page only displays 3 posts, which I do not want to place ads in, but the previous posts, are just getting search traffic, and I am not monetizing it at all.
What would anyone recommend that would not interfere with the Affiliate programs that I already have?
Or, would a CPM program be better?
