We like the idea of a fireman's maltese cross, but are not tied to that necessarily. 

We also like the idea of using a Dalmation because the vehicle that hauls the equipment around is a Firetruck. Attached images are the vehicle the company will use. It will be green, not the red it is in the picture.

We also like the idea of a superhero holding a blasting hose, maybe to look like a comic book style

We do not want all three combined, these are just some general concepts we came up with. 

The colors will be Green #1daa4a.
