I would like to ask your opinion about a new idea: we would like to create a free guide / ebook for the more advanced DJ / Producer. The idea is to create one, with tips and tricks how to promote yourself online/offline on Facebook, Twitter, website, clubs, event managers and other marketing techniques. On the internet there are several 'dummy' ebooks how to start with deejayen - but not especially for the more advanced clubDJ.

The ebook / guide will be completely free to download!! I would like to ask you guys for more ideas regarding this ebook.
What chapters / items would you read in this ebook?
