Logo for excavating business

I am looking for a professional logo for an existing business in the excavating industry. The logo should be able to capture the essence of the company and make us stand out from our competitors. I am open to any creative ideas, so please feel free to be as imaginative as you can in coming up with the right design. I am interested in a combination of text and imagery, so if you are able to combine the two in a clever way, then that would be great. I look forward to seeing your proposals!
