Was in a similar position to you actually - I got an offer from Packt to write a book on ElasticSearch. I've learnt that if you write a blog piece about some obscure/hot tech and articulate yourself well enough; you'll get an offer from an author head-hunter from Packt shortly enough as several of my friends had similar offers!

I decided not to go ahead because I'm a perfectionist - I'd want to write a damn good book and the opportunity cost loss of earnings whilst I was writing the book didn't compare to the relative prestige of saying I was a "published" author.
