Andy Adams released a book for aspiring WordPress freelancers. It's meant to take a lot of the guesswork and the roadblocks that many folks often hit when making the decision to fly solo and rely on WordPress development for a stable source of work and income.
Aside from being included in it (and Andy being an all-around great guy), I want to share the book with y'all because WordPress and freelancing are two topics I care deeply about, particularly because the WordPress platform and community helped me crack into freelancing when I made that decision five years ago.
What I've seen over the years is a delta between what is perceived about WordPress freelancing and the actual reality of it. Sure, all you need is a computer, a text editor and a free download of WordPress to get started. That's the easy part, but there's much, much more that's worth considering. Finding clients is hard. Managing those clients is hard. Pricing work is hard. Proposals are hard. Taking time off is hard. These are among the things Andy covers in the book and the advice he provides is something that will benefit anyone breaking into freelance work.
