I came across this website where David Parrish is offering a free downloadable ebook for the artist and creative entrepreneurs among us. The original book was published in 2005, reprinted in 2006 and is still available in paperback as well as eBook format.
According to his website "The eBook is the full version of the book 'T-Shirts and Suits: A Guide to the Business of Creativity' by David Parrish in interactive PDF format. It can be downloaded free of charge from this website."
It quick and easy. Check it out.
