If you've chosen a non-optimal solution I'll correct it and suggest a more efficient way. I'm never promising something that you're probably expecting to hear instead of the realistic estimate of your project. I'm never lying to my clients and I'm always giving all the information which I have - transparently and on a regular basis. In one word - you can trust me as you trust yourself.  less
