“Your website clearly showed that you did small jobs like mine, as well as much larger ones.  Leigh-Ann was very professional, knowledgeable and did what she said she would do.  Other companies that I contacted either didn’t get back to me as promised, were vague about the process or just didn’t seem interested.  Michael Aubrey structural engineers completed my design as requested and submitted the documents to Building Control on my behalf which saved me the worry of whether I’d done it correctly.”
