Query: Great Ideas for Niche Income

There are plenty of ideas here for how to earn some extra cash (or even make a living) starting from scratch with no skills and limited financial resources. The author points out that some of the best sources of income are timeless (people gotta eat!) and that anyone willing to put a minimum amount of effort into it can make it happen.My only complaint (and it is a small one) is that, since written in 1997, the book excludes any computer or web-based businesses. But on the other hand, I find that refreshing!
