Logo for start up construction company

I'm looking for a creative logo design to represent my new construction enterprise. That Building Group. The logo should reflect the core values of the business, and any colors used should be black and green, or black and white. I am open to suggestions for symbolism or imagery to incorporate into the logo. This project is for starting a new business, and the logo will be used for business purposes. Experience in logo design is highly desired. Please include samples of your previous work with your bid. Thank you in advance for taking the time to review my project.
