As an academic group, we wanted to improve the look and feel of our website on a tight budget. The team at Project Ricochet was consistently responsive to our concerns and willing to help us meet our goals. They were transparent with their costs, which allowed us to pick and choose which features and changes we deemed most important. Thanks to this transparency, our new website is a substantial improvement over the old that we were able to achieve in a cost-effective fashion.
