Sounds like you are starting in an already established market? That can make it tough right from the start. As a publisher, I don't want to waste time on a new vendor or product. I want established products that are going to convert into sales. It is a common problem any new product face. I would first work to make it successful via Adwords and marketing. Once you prove it sells, you might get more interest from affiliate marketers. You can offer 100% rev share and folks won't sell it if they are not sure anyone is buying it.
