Market research for Kindle?
If you think you have a good topic for publishing an info book on kindle, how do you go about finding how warm the market is?
Lets say for instance, one of my plans was to write a book on "how to get into the fire service" a specialist subject for me and something that would be of great use to thousands here in the UK! I'm not sure about other countries, but here each brigade has thousands of applicants every year for only a small number of vacancies, and I know I have the knowledge to give people the edge over their competition! but how would I find out how warm that market is? there are no forums or chat rooms on the subject really, so how would you recomend reaching out to these individuals?
......and not just that, in general do you Kindlers do market research before writing a book, or do you just run with it and market it the best way you know how?
Thanks in advance you lovely warriors you!!
