consultation was more like a sales pitch, would have expected him to advise how to connect things rather than sell me. didn't get any value from it. he could give value on the calls rather than selling.

Colin was excellent to work with. He was patient, professional, and took the time to help me understand the process of setting up my social media AI agent. Any delays were mainly on my end because of my busy schedule, but Colin remained understanding and supportive throughout. He did a great job, and I would gladly work with him again. Highly recommended!
