The product must have some value for marketers although it doesnt need to be top notch. Keep it simple.
* price it very low so that you get MANY sales. A price like $5.95 for a collection of 100s of PLR articles, something like that. Make it so its a no-brainer that people buy it, price shouldn't be an issue.
* Put product on clickbank
* Send out to your targeted IM list (which are all marketers and people interested in such products)...promote on webmaster forums.
* In addition to the low price make it even more attractive by leaking the "secret" that every marketer can actually get the item even cheaper by buying through their own affiliate link. (This is allowed, by the way.)
There is a high chance that many people in your list are on clickbank since they are all marketers anyway..so encourage them to use their afflink.
The result is a "gravity explosion" for your product on clickbank since so many IMers will get this using their own affiliate link.
* Once your gravity reached some crazy number you put your site up for sale and sell it for a lot of $$$. Advertise it as "super high gravity best selling CB product" etc...etc...
