Hi Suke,
I really like the shield concept, but there is something about this design that needs to be adjusted. I found this logo from another site and like how they put the homes in the shield and put the name over the shield. Can you take your design and put Leslie over the bottom of the shield with some type of home roofline in the shield like this design. Then Heating and Cooling underneath the shield? And keep our colors in the process?
