Basically as a freelance client hiring a freelancer is a weird proposition because you don't know what you're getting before it's too late. Productized services take care of this because they outline exactly what you're getting before you buy.
This is a book I wrote over the course of the past year. I started Workshop, a service that helps freelancers find work. A lot of members made a lot of money but there was also another group who made nothing.
I found out it was because of the emails they were sending, not their level of freelance work. So I started working with everyone individually and extracted the lessons from those sessions into this book.
I run a private newsletter full of awesome freelancers. It's free for a limited time and I'm sure I can get you 5+ awesome freelancers to email you by tomorrow afternoon, just post your project here: http://letsworkshop.com/connect
