Like Martijn Scheijbeler already said, this should not be run by someone with "a lot" of experience managing an affiliate campaign. If done wrong you can cannibalize your own sales, and worse. I would recommend MaxBounty to anyone. They have dedicated management teams for both advertisers, and affiliates.

As an alternative, you could seek out successful affiliates directly, and give them an exclusive offer, a relistic incentive. hint hint mike [at] informlocal.com

The benefit to the advertiser is a win win. They don't have to outlay money for ineffective advertising, and they get new customers. As the advertiser you have to set the ground rules to protect your self, or only deal with an reputable company, or individual affiliate like me.
