You're big mistake is that you optimized for your company name instead of your keyphrase target. i would redo the title, meta, H1, testimonial, and description on bottom and make sure it has your desired keyphrase in it and don't muddle it up with the word "based" inbetween taxi and Knutsford. Even doing this right is not sufficient, make sure your properly launched into Google local and get some quality external links with the keyphrase as the anchor text.
Good luck.
