GEN2 Plumbing Systems - Creating company logo

This is what GEN2 Plumbing Systems Inc was looking for in their logo design

-Looking to create a company logo
-I added what i have in the upload box but i want a little more. Im not sure what but its needs a little more. Maybe a little depth?
-I like the "GEN2" to be in bold square boxy letters with the "Plumbing Systems Inc" in a smaller font below.
-I'm also open to new ideas.
-The business is new contruction plumbing, NOT service plumbing

Add'l notes:
What do you feel is missing overall from these submissions? ?
- I’m open for the artist to be creative
- incorporate a G2 some where in the design. I do like the American flag.
- I might like some shadows effect

Are there elements that you do not wish to see being used in the design? I didn’t like the house logos. We are construction plumbing (not service plumbing)

On Colors:
- I do like the grays and blues but I’m open to other solid colors Read more
