I was working full time for a company vetting applications for a certain type of job. It was a very desirable job/career and we were always on the lookout for new talent so by the time I left a few months ago I still had access to my company email address with about 2500 applications (email address, phone number, home address, age, etc). I figured there was some kind of way to monetise this and I'm quite knowledgeable on the industry so I wrote a short ebook about how to break into the industry. I put it on Kindle and figured I would make bank. I sent a bulk email to all on the list about how amazing the book was and over the next few days a steady stream of sales came through. But it wasn't exactly mind blowing or life changing, it was about the equivalent of working a 40 hour week in a normal job. And of course with Kindle I had to wait ages for them to pay me. It was anti climatic to say the least. Anyway I wanted to carry on selling the book because I was proud of it. So I posted ads on free sites like Starnow, Gumtree, etc pretending to be hiring for a job within the industry. After a couple days each ad has 20-30 responses and I send a brief message saying you have been selected for a telephone interview, to prepare i recommend you download this ebook. About 1 in 10 go to amazon and download. This has been a pretty consistent figure and isn't bad considering that you need a Kindle to download it. It's quite easy, it's a decent niche, a good book, and just a case of copying+pasting the ads and follow ups and you get a steady stream of Kindle income. Question is how can I grow this? Is it worth building a landing page with a pdf download and buying some adwords. Or something else? I'm quite new to IM so all thoughts appreciated and if you think it's a bit of a dickish thing to do then feel free to let me know as I kind of agree it's just I went to a lot of effort writing the book and wanna make something from it.
