I cannot speak more highly of Peiko. My initial trepidation in hiring an agency in another time zone, and a market I was not familiar with, proved unfounded. Always professional. Incredibly switched on. I don't have to explain everything - they intuitively seem to understand, and then go the extra step to improve on my requests. We have been so impressed with Peiko that we have expanded the project to a second site, and in the hope things continue the way they have, any future sites we build
