eBook Digital Marketing Campaign

My project nearing completion is an eBook entitled Mind Afire. It is a compilation of essays addressing simulation theory and the nature of reality. The book will be finished in a couple weeks, so I am currently trying to create a pre-launch campaign. I am looking for someone to help me with my digital marketing endeavors to attract visitors to the landing page. Ideally this would be someone who has written multiple eBooks and knows better than I the process of creating a successful pre-launch campaign. This assistance could be a one-time advisement session, or a series of shorter sessions spread out over the next couple weeks until the eBook is released. Or if your skills would be better applied in some other format concerning the project, I am open to your ideas.
