Guys, I need help from people who have experience with the following..

One of the biggest players, contacted us with a request to buy banner spots across our entire network of adult sites. And here comes the problem. We do not sell ad spots and generally prefer to stay in our role of ordinary affiliates. On the other hand, the company is too big and we don’t want to miss that opportunity.

So we have to make some sort of decision. One option for us is to work with them directly, but we do not have the necessary experience. The other option is one of the ad networks that take care of everything about advertising. The third option is to deny them politely, but I don’t think that would be wise.

What are you doing in a similar situation? Do we have to make an exclusive offer to them? Or maybe we should choose the services of a company that deals with that?

Thanks for any feedback.
