The freelancer's bible (Sarah Horowitz)
Since an internship a while ago I got encouraged to think about how to increase my freelance business. As a foreigner in the States, it is natural that I did not have any glue in the beginning how this freelance system will work. Many laws, rules, and regulations are quite a bit different so it was necessary for me to make some research on my own how I can set up a freelance business. This book was very helpful for me on collecting ideas, facts and giving me a direction on what steps I have to follow next.
