You're actually hitting on a special niche that I'very been working on.
As it has already been mentioned, there are a lot folks with the expertise and experience who have either marketing and sold their own product or do if for others for a fee. Their models are fine, but they don't help people like yourself.

I propose that you look at this from an investor's point of view. What is the market (size and description ) and what is the product (What is unique/value prop)?

If there is value there, I suggest instead of a commission proposal, you make an equity play. Give partial ownership (or at least revenue share) to someone who is willing to create the remarketing engine for you.

If your content/product shows promise, and you've done your homework (building email list and Web site), you should be able to find someone willing to risk their time/effort for you.

Like me. :)
