I've worked with many designers on 99designs and ZivDesign is hands down the best. We've done multiple projects with him and he surpassed our expectations on every single project and on every single design. He comes up with better designs than we hoped for, made any changes we asked for, took our briefs and made them better. The handovers were smooth and fast and and Ziv gave us everything we needed and more. We have worked with him through 'competitions' and on further projects (including this one) using 1:1 invoicing.
This guy is real professional and a wise choice for anyone who is looking for a GREAT designer.
