Long time freelancer recently gone business owner. In all actuality nothing has really changed, I just have a payroll now.
Chicago resident of 10 years, with 15 years background in graphic design, motion graphics, and web design. In the last 9 years, I began focusing on marketing and social media, and within the last 2 years I've been adding coding and web development to my skill set as well.
I specifically, but not exclusively, work with small to medium-sized businesses because as a small business, I know how hard it can be to find quality work and it still be affordable.
What makes a good business? Be good at what you do, have integrity, be honest, and treat people the way you want to be treated. Simple enough.
