During our work together, Jim has been an intelligent, capable, professional partner in this endeavor. He has acted as a valuable sounding board as I try to figure out just what is necessary as well as what is possible. He works hard... at times I've been astounded at how quickly he can turn a concept into reality. He has been honest in his dealings with me. I could not be more pleased with his effort, demeanor, and results thus far.

Extremely helpful in offering alternative ideas. Was 3x faster in building prototype than all other bids.
