A great way to begin a career in sales is to start out as an intern. This is a great way to gain experience and make all the connections needed to pursue your career. First you would want to apply to as many companies as you can. Also check out Craigslist under art/design. Before you go on the interview do some research and familiarize yourself with the company and their image and mission. Finally, you want to dress the part for your interview, so be stylish and professional, but don’t overdo it, you want your first impression to be professional.
