    Expert writing for the busy entrepreneur

    United States - Last active: 9 days ago - Tests: 2

    You need someone who quickly understands your needs, reviews your materials, asks intelligent questions, understands the answers, and lays out your thoughts and ideas clearly and effectively. You need RESULTS NOW, if not sooner. You don’t have time to educate a generic writer without the background to climb that steep learning curve quickly. “Incredible attention to detail and the ability to thoughtfully lay out complex ideas and concepts into an eBook that will give those with no experience in the subject a primer. Final product was provided ahead of schedule on a busy holiday week. We’re already talking about our next project.” “Opher did an amazing job. Took personal interest and delivered exceptional results. Went above and beyond what was initially agreed, focusing on nothing other than project success. Highly recommended when you want to get things done.” “Another amazing project with Opher! He’s fast, efficient and extremely talented. I'm about to hire him again."

    Graphic Artist

    Canada - Last active: 1 day ago - Tests: 2 - Portfolio: 3

    Born and raised in the province of British Columbia, Canada. I have been a freelance graphic artist for approximately 11 years. My primary focus has been in logo design and brand/identity development. I have always been intrigued by the artistic world but my logical brain is also very strong and drives me to play with numbers to no end. These two personality traits are why I have always felt at home in the world of design. Whether it's colours and tint percentages, to shapes and letterforms in ratios and fractions and calculating the negative space in between. The constant equations between form and function. That's the process.
