Write an eBook and a sales post

Hello, I am looking for someone who is proficient in internet marketing to write me an eBook that is suitable to be sold on the DigitalPoint Marketing Forums. He or she should write an eBook on a topic related to internet marketing that has a high chance of selling, but also contains legit, unique and useful information (not sub-standard content). He or she should then write a post that I can place on DigitalPoint that advertises this eBook (marketing skills required). You will only be paid if I manage to sell at least one of the eBooks (price: $10). No upfront payment. Please note you must write the eBook yourself, I do not accept plagiarised/copyrighted work. All rights to the eBook will be transferred to me as soon as I have received it. Great marketers/writers should be able to handle this job.
