Go with your gut then. 1:3000 in dating for any clicked traffic with a halfway decent link or banner which isn't mostly Googlebot traffic is not acceptable. There is something wrong somewhere and it's probably not your pre-sell although some people gave you good advice.
Promote 3-4 different ones and then send the most traffic to the best performing one and a little each to the others. Re-evaluate every month or two. Repeat. It helps keep them honest.
