Walter ElectricLogo Design Contest

We provide residential & commercial electrical services. I am currently refocusing the company towards residential service work.

I have an existing logo that I am looking to redesign and update a little bit. Maintaining our existing color scheme is important to me, I may be interested in adding a graphic and I do have some thoughts on that but also totally open to suggestions.

Green
Brown
Beige
White

I would like to modify the font & style of my logo slightly to provide a similar but newer & more modern appearance. I may be interested in adding a graphic or character if we can make it work, I just cant picture how we would incorporate this with my logo. Although a graphic is NOT my primary focus at this time here is some graphics I am interested in:

-QR code
-House "similar to the Nest logo" with leaf's coming out of the chimney
-Possibly a character
