Nice work - thank you for taking my comments into consideration with these logos.
#6 - Would like to see this design in different colors.
#9 - Would also like to see this design in different colors. I like the colors of the trees and sun, but would like to see the Lake Cook name in different colors. Also, please place the word Plumbing not in a banner.
#8 - I like the colors of the trees, water and sun, but the sun looks like a moon to me. Can you please fix that? Can you also make the word Plumbing bold? Can you make the words Lake Cook dark blue?
