a couple of years ago i was approached by a publishing company, they said they wanted to publish a book and i could be the author blah blah blah , there was a fixed fee and no royalties, the money they were offering was "just" considering the work involved, they then asked me would i be so kind as to furnish them with a ton of ideas in a virtually finished format. for a much smaller fee.
the deal wasn't a deal at all these guys already had a publication in the works and they were fishing for ideas to fill it, the book was published shortly after, never bothered to find out if it was any good or not.
a small clue to the content with my last uploads
all the best folks
