Just wondering if there are any e-books about e-book creation online in which I can improve upon my skills of writing an e-book, promotion, etc.. Currently I have created a couple e-books within the past couple months and so far they have been bringing me a little residual income monthly which is a sale every 2-3 weeks of $20-40. This is no where near what I want to be making as an extra on top of what I do already... I am looking to bring in an extra $100 or so every 2 weeks. Anyone have insight on how I would do this? I am hoping someone who has created e-books on here for personal sale / customer request can give some input.
