I am selling 6 125 x 125 spaces on my business site at a similar location to techcrunch as well as 4 50 x 125 spaces next to the title. The rate for each ad is $10cpm counting uniques. The ads will be sold in one week blocks; at the end of the 7 day period I will send you a report of the uniques I got and you will then pay me based on that. I will start counting only after 7 spots are taken. Thanks! Please post here or pm me with any questions.
