I have a product/service that is a complete membership site teaching seo, ppc, web 2.0 marketing, with full support and training. The price is $497 and I am offering $250 commissions on any sales. I have had success selling this B2B. There is a version geared towards the avg internet marketer that will go for $97 ($50 payout to you). Obviously the one on one training and some other features are not available.
I also have 26 other pieces of software that includes auto submissions (Article directories, directories, rss feeds, social media, video, and more), content management, site translation, and others.
All legal methods welcome.
