    Freelance Illustrator/Graphic Designer

    United States - Last active: 1 day ago - Tests: 7 - Portfolio: 26

    All-American. And, always excited to help you with your graphic design and illustration needs! MY EXPERIENCE: a variety of printed pieces, online graphics, logos, PowerPoints, videoscribing . . . ALWAYS on time and budget. Let’s discuss your expectations today! The "jobs in progress" number does not necessarily mean my time is unavailable. It indicates open contracts for the convenience of my clients who only require occasional work from me. The "Job Success" percentage number is completely inaccurate and a total misrepresentation of my work and relationships with all my clients. Not one of my clients, in my entire career, has ever been dissatisfied with what I have produced for them. I've received payment for every bit of work I've ever done. And, aside from the contracts that are currently open, all contracts have been completed. Only one client was favored with a complete refund because he accidentally paid me twice! :)
