Best ServiceLogo Design Contest

We are a top of the line "Nordstrom Style" provider of electrical, plumbing, heating, and air conditioning services for residential customers. We are rebranding and need a logo that is recognizable and reflects the professionalism and distinction of UPS or FedEx. This logo will be used on the side of a truck and must be seen and recognized while traveling at speeds in excess of 50 miles per hour. The logo will also be used in all forms of digital and print advertising as well as our website and various social media outlets. Attached is a picture of a shield, which we'd like to use as our mark, but it needs to have our own twist put on it as this is a generic picture of a shield found on Google. Our background color of our Truck is a very vibrant almost lime/fluorescent green as can be seen in the attached picture of our current logo.
The main logo points are below:
-Bold, crisp, professional, unique
-Rich blue color
-Semi 3D

Rich Blue

Our Company colors are green and blue. We intend to use the logo with a lime/fluorescent green color as can be seen in a picture of our current truck, and our website @ www.callbest.net. The primary color of our truck could remain green.
