I've been working with them for about seven years now, but we have only just recently started using their logo services as well. They are extremely professional and helpful! Nothing so far! If you need someone who will listen to your needs, they do that very clearly. Keep in touch, if this works out, then it's going to be great! We're looking into having our corporate identity designed by them. We want something simple, yet visually impactful which can stand us in good stead through future company changes.
