I'd like to start mixing adsense ads and other ads (affiliate, 3rd party networks, house ads, whatever).
I am basically looking for a server (ideally, externally hosted, but I'll also consider installing a software package) that would take HTML code for the various programs and give me a single URL of an ad block to put on the page.
The block would display something like that (just an example):
40% of AdSense 30% of House Ads 20% of Affiliate Ads 10% of other network ads
My question is very simple: where do I start? Are there any good 3rd party serving solutions that will do that for me, preferably with reporting? Are they expensive? Would you mind sharing positive/negative experience?
(If URL's are not allowed, the names will suffice)
