I decided to keep the "G S" idea from your original logo but update it with something more upscale looking. A small wave replaces the normal serif on the "G" and connects the G and S together.
I used the same green background color as the top of your website (color matched to the darker gradient at the top of the your website). And it's the correct dimensions to fit right snug into the banner of your website and leave room for a tagline or some photos or a phone number beside it.
Would like to refine this design further adding some more color and detail, but here is the beginning of a logo that I wanted to show you.
I apologize for not having time to finish this off before you marked it Not Interested. Here is a more polished version with the custom "GS" shape, and the icon in the shape of a key.
