"Do yourself a favor and find another engineer. James is a nice man but for the rate he charges, i would expect far better service and quality of work. Since day one, i had to continually remind him (more like nag him) to do the things he committed to do (i.e., send proposal, get measurements, send drawings, etc). And when he finally sent a draft of the final drawings (for what is a very simple project), I couldn't believe the poor quality and attention to detail. And with each subsequent draft, it seems he introduced more errors than he corrected. "
